As summer approaches us here at Kryton in Canada, we know that many of you will be planning your hot weather concreting. While the weather can be a joy to experience for yourself, it can also make concreting more challenging.

For one, high temperatures will accelerate the early-age strength gain of your concrete. This sounds like a great way to naturally expedite your schedule. But it’s hard to take advantage of that when you aren’t sure of how fast your concrete is developing.

Moreover, once high temperatures get excessively high, your concrete can develop a number of durability concerns. For instance, it can end up with delayed ettringite formation (DEF). And DEF can be quite a destructive force in moist environments as it can cause your concrete to prematurely deteriorate.

Outside of DEF, your concrete can also experience drying shrinkage. This happens when the concrete has suffered moisture loss after hardening. It increases the concrete’s tensile stress, raising the likelihood that the concrete will crack or warp.

All of which is terrible for constructing a solid, reliable structure. However, you can reduce the risk of this happening during hot weather concreting with our Maturix Smart Concrete Sensors.

So, How Do Maturix Sensors Help?

They give you an easy way to stay on top of your concrete’s thermal control plan. Once connected to type K thermocouple wires, which are positioned and attached to reinforcing rebar, the Maturix Sensors wirelessly transmit temperature data to a cloud-based platform every 10 minutes. Then, the platform takes that data and calculates the maturity based on the readings and a specific concrete calibration curve. In return, you get a result that accurately determines your concrete’s current strength. All of which allows you to tell exactly what temperature and strength your concrete has every day. And because this information is transmitted wirelessly, you can access it through any connected device, keeping you up-to-date on the situation, no matter where you are. Additionally, you can easily set up alarms to receive notifications via SMS or email when a certain temperature, strength, or maturity has been reached.

That in turn allows you to stick to the recommended temperatures for hot weather concreting and operate proactively as specified in ACI 305R: Guide to Hot Weather Concreting.

Of course, that’s just the start. There are a couple other advantages that come with Maturix. Let’s take a look at them.

They Enable You to Leverage Early Concrete Strength in Hot Temperatures

To start, with the insight they provide on strength development, you’ll notice right away when your concrete starts reacting to hotter temperatures. After all, you’ll see exactly when the concrete’s strength accelerates. So you’ll be able to plan your schedule to work with this expedited strength development. In turn, you’ll find yourself stripping forms at a faster rate, letting you keep up with any tight deadlines you have.

nd Their Real-Time Alert System Makes It Easy to Avoid Potential Temperature Concerns

You can set up this alert system to notify you and your team when the concrete meets, exceeds, or goes below critical thresholds. So long as you have a connected device, you’ll immediately know when your concrete is doing well and when it needs adjustments. That way, if your concrete ever exceeds recommended temperatures, you and your team can take the required actions to cool it down.

In short, Maturix empowers you to fix temperature concerns before they ever become a problem.

Why Choose Them Over Other Available Sensors for Hot Weather Concreting?

Still, there are other sensors out there. What makes Maturix worthy of more consideration?

Well, Maturix comes with a number of unique features you aren’t likely to find elsewhere. Some of which include the following.

You Get Local Weather Data as Well as Temperature and Strength Data

To further bolster your understanding of your concrete’s development, Maturix Sensors gather data about the local weather. That way, you don’t just know how your concrete is doing. You also get a sense for what conditions your concrete faces throughout your construction project. Whether you have to deal with hot weather and rain or any other weather combination, you get the weather data integrated in your reporting.

You’ll Even Be Able to Reuse Maturix Sensors for Multiple Projects

One of the best cost-effective measures of these devices is that they don’t work like single-use sensors. These aren’t disposable devices that remain within the concrete. Instead, they are connected to disposable thermocouple wires. As a result, once you complete a project, you are free to take the sensors with you and use them for other projects for as many times as you like. This allows you to take advantage of all the features Maturix offers at a low cost. After all, you don’t need to spend a big chunk of your budget on new sensors with Maturix.

In the end, Maturix is a worthwhile investment that cuts down on your costs and makes hot weather concreting much less risky.

So Why Not Give Them a Try for Your Next Hot Weather Concreting Project?

If you’re expecting to deal with such a project soon, then it might be time for you to find out how advantageous it can be to have Maturix with you. You’ll soon wonder how you could have gone so long without it! But don’t just take our word for it. Check out our Maturix page to see for yourself.

Providing the best results for clients: that’s what most contractors strive for. And Kruse Smith is no different. That’s why the Norwegian contractor has recently started digitalizing their work for the E39 highway project. As part of this process, they took a special focus on technological innovations and how those could improve their on-site performance. That has allowed them to minimize any repetition, time consumption, and labor costs associated with their work while producing more cost-effective and timely end results.

More specifically, it has allowed them to effectively develop the 19 km (11.8 mi) of the E39 project that they are responsible for.

However, the project as a whole is likely to be the largest coastal highway infrastructure Norway has ever conducted. At about 1,100 km (683.51 mi), the project is expected to replace multiple ferry travel points and cut down travel time from 21 hours to just 13.

To optimize their part in this extensive project, Kruse Smith conducted a digital pilot project, enacting innovative changes, such as replacing paper plans with 3D modeling and BIM and using wireless sensors for concrete monitoring.

These wireless sensors (also known as Maturix Smart Concrete Sensors) help optimize Kruse Smith’s work on-site by enabling the contractor to remotely monitor the temperature and strength development of multiple concrete structures in real time. It’s a method that saves them time and money that they would have otherwise spent on physically checking each concrete form.

For more details on how this innovative technology is helping the contractor move forward on the E39 project, the creator of Maturix, Sensohive Technologies ApS, conducted an interview with two members of Kruse Smith’s team, Marius Røksland, and Asbjørn Stålesen.

The interview gave great insight into the use of Maturix in the infrastructure project. And we are happy to add to the conversation, sharing additional interview details on how Maturix helped Kruse Smith in their everyday work.

To talk about Kruse Smith’s work on the E39 project and their use of Maturix, we have two members from their team. Can you tell us a little bit about yourselves?

Marius: My name is Marius Røksland, and I work for Kruse Smith as a project engineer.

Asbjørn: I am Asbjørn Stålesen, and I’m the project manager for the new E39 between Kristiansand and Mandal.

What are you currently working on?

Marius: At the moment, at this jobsite, we are building 19 bridges, completing the new E39 highway. It’s a four-speed, 110-kilometer [68-mile] highway on the coast of Norway, all the way south. It is one of many small stretches of roads that we have been constructing.

For this one, now, we have been working for a couple of years and still have one-and-a-half years to go.

This bridge is about 370 meters long. It’s a dual lane, so we are doing two at the same time.

How far are you with the bridge?

Asbjørn: Currently, we are 90-, 95-percent finished. We have cast all three bridges, but we have some of the small works around them left before we can hand them over to the client.

On this particular project, we have all cast-in-place. We have no precast, and we do this with quite big formworks.

These are 120-meter [393.71-foot] bridges, but we reuse the formworks from one to the other. So we try to do as much of that as we can, but it’s important for us to think industrial scale because we’ve been building so many bridges in such a short time. This is also why monitoring the curing process enables us to move on a lot faster as we know exactly when we can remove the formwork.

What are the challenges of this project?

Marius: The weather is a challenge as it is way too cold. We have problems with ice and snow here in Norway, especially now when it’s so cold. So it’s important for us to know the concrete temperature in the whole bridge and every cast. This has mostly to do with the maximum temperature, but also now in these conditions, we really have to be careful not to have anything freeze until we get the curing.

There are also different aspects, but mostly, that the temperature may not differ too much from the core to the outer edges as the structure can get damaged otherwise. In the current temperatures with the cold, it is a challenge. So we really need to monitor the temperature!

Did you always monitor the concrete temperature in mass concreting?

Asbjørn: It’s always been a requirement that we monitor, but the other systems we used were offline. That means that you go and collect the data and you come back and analyze it.

This also means that in real life, you do this more than one time — maybe once if you’re lucky — and directly get the required result.

Marius: Before Maturix, we used manual data loggers. They were digital, but not wireless. Then, you had to take the sensors, set them up, leave the sensors, cross your fingers, and hope for the best. And then, some days later or some hours later, you have to go back out to the form, check whatever reading there is, collect it, put it into the computer, and see what you actually get.

Asbjørn: So even with the data loggers, it is still very time-consuming to set them up and go get them. Also, you really don’t know what the data looks like until you actually finish the casts and do the analysis. (With Maturix, you get all the graphics and analysis on the screen — live.) And you don’t get any chance of doing something as you progress through the curing process.

That means that you’re not really actively using the data. You’re crossing your fingers and hoping that everything has gone well, and afterwards, you have documentation that it did. It’s a very passive way of working compared to having the data available at all times.

How do you actively use the data?

Asbjørn: So that’s one aspect of it — better active documentation and quality control. Another is, if we forgot something and suddenly there is a change like a temperature drop or some kind of temperature change or another concrete mixture — or if it gets too hot, for instance — or you were expecting to see this curing process start in, say, eight hours, but you didn’t get it until it was 14 hours? Then, we can investigate further why and potentially save time next time by adjusting the mixture or doing some additional work prior to casting.

So, are you using the monitoring data to optimize future casts? Has that influenced internal teamwork?

Asbjørn: Yes. We see that in everyday life, we’re using the data so much more, and discussions around it have been brought up. The temperature data becomes an everyday topic instead of being something that a quality engineer does and documents. And we see that the data has been actively used to improve how we build.

How important is the monitoring data for you, and how do you use it?

Asbjørn: It’s important for us at all levels. For me, as a project manager, it’s important to keep control of all the work going on. We have work in a lot of different sites, and this enables me to keep track of ongoing castings and how they are doing. So basically, we can monitor the situation in real time so that we know what’s going on.

But it’s also important for us in everyday work, where we have control over all the curing processes at a much better level now. And we can much more accurately predict when the concrete is cured and when we can go to the next step.

But it’s also good from a quality aspect. We can use it in meetings and discuss how the castings are going and which areas of concern there might be or how we can adjust for future casts.

Marius: We can check whatever the concrete is doing and share the information with the client. That creates a lot of transparency and trust.

Who has access to the monitoring data?

Asbjørn: Well, we have chosen to share the access to the software with both our clients and third-party members. So everybody has full access to all the data, and the feedback from that is very good! They check the data, and they discuss it with us. We have a very good dialogue with all parties, and we get to share the knowledge of how to improve our quality of work.

It gives a whole new level of trust, showing them that we have nothing to hide. And this is very good to have in a project like this!

So, how easy do you think it would be for someone who has not used Maturix before to get started?

Asbjørn: We’re finding now that it doesn’t take much training at all and that people are really on board. People are really interested and want to use it as much as possible here, and it’s certainly not a system we will go away from.  It has come to stay with us.

Marius: You just take the cable, connect it to the transmitter, start it in the software, and you are ready to go. It’s super easy to get started.

What would you tell someone who is considering Maturix?

Marius: I think it would be better to show them. You get everything that you need, plus a lot more! You get all the data and don’t need to be on-site or do the analysis, so it just is better and quick and easy.

Asbjørn: I’m firmly recommending using the system. It gives you much more insight into what you’re doing. Also, together with your client, it gives you better client relations and a higher quality of work. So in my mind, this is the way forward!

Thank you so much for taking the time to talk with us, and good luck with your work on the E39 project!

Ever thought about what it takes to keep the water you drink and the water you see outdoors clean? It’s not often considered! But there are companies who work tirelessly to make it all happen. Aquatera is one such company. Since 2003, they’ve acted as the owner and operator of water and wastewater treatment and transmissions systems for the City of Grande Prairie in Alberta, Canada.

Under their direction, Grande Prairie’s citizens have been able to enjoy safe, clean drinking water and ensure that their wastewater returns fully sanitized back to the Wapiti River. It’s a direction that worked for a decade.

However, by 2013, Grande Prairie’s population had grown by more than 18,000 people. While that was great for the area’s economy, it left Aquatera’s plant running at full capacity. If the population grew any further, the plant would not be able to accommodate the increase in demand.

Determined to leave no person without their essential service, Aquatera chose to expand their plant.

quatera’s Expansion Would Involve Multiple Additions to Their Plant

It would also cost a pretty penny! For over $58 million, Aquatera would be able to fully upgrade the plant to include the following:

Two new biological nutrient removal reactors (BNRs)Two new circular secondary clarifier filtersA new centrifuge building

While this upgrade would be expensive, the end result would be priceless. These additions would give Aquatera’s plant two major benefits that would keep it running throughout Grande Prairie’s ongoing growth spurt.

They Would Help the Company Meet Current and Future Regulations

As a company that handles the water and wastewater treatment for a whole city, Aquatera is beholden to a number of rules and best practices. These come in the form of provincial and federal regulations and guidelines. And they also include individual municipal utility bylaws from four shareholders.

Of course, it also means that Aquatera needs to periodically update their system to meet the latest standards. Taking that into account, Aquatera knew they’d need their upgrade to address this. That’s why they chose to add two more BNRs to their plant. Both would allow them to satisfy the needs of Grande Prairie and meet current and future regulations surrounding those needs.

nd They Would Also Increase the Company’s Overall Efficiency

More importantly, all of the additions to Aquatera’s plant would give it the ability to work more efficiently. For instance, the plant would be able to treat 12,000,000 more liters of wastewater a day than it would have before. To put that into perspective, the plant’s original capacity limited the plant to treating 22,000,000 L of wastewater a day. But with the upgrades, the plant would be able to treat up to 34,000,000 L daily.

On top of that, the upgrades would also increase the plant’s sustainability. They would give the plant a longer life span while reducing how much power it consumes and how many greenhouse gases it emits.

Combining this new capacity increase and sustainability enhancement meant that the plant would be able to work in a more eco-friendly manner while having the capacity to serve a growing population.

But These Upgrades Came with a Couple of Challenges

While Aquatera was eager to start upgrading, they had to make sure their construction team would be able to complete the project on time while working in Alberta’s harsh wintery conditions.

With that in mind, it was clear to them that working with concrete in such a climate meant they’d need a time-effective solution that could give them both permanently waterproof and highly durable concrete. And this solution would need to be able to handle significantly cold temperatures over the winter season. In short, it would have to be an innovative solution.

They Couldn’t Go with a Conventional Surface-Applied Solution

Traditional solutions like surface-applied concrete waterproofing and hardening products are costly and time-consuming. After all, crews need to be scheduled to handle the application. And that can involve the need to spend more to hire extra workers and expensive equipment. Even if all those costs could be managed, it still means waiting for the workers to finish their manual application.

At the same time, that process adds the risk of application errors. No matter how well trained a manual applicator is, they’re only human. So there’s always a chance that the application will not uniformly cover the concrete. And that could leave weak spots in the finished concrete structure.

If Aquatera wanted their concrete waterproofing and durability solution to be both timely and cost-effective, they would need to look elsewhere.

They’d Also Need to Be Careful of the Weather

No matter what they chose as their solution, the construction team would still have to make sure that it could handle the wintery weather. With surface-applied solutions, that could prove to be difficult. It would double the amount of heating they’d have to worry about after all. Both the solutions themselves and the surrounding ground would need to remain unfrozen. Otherwise, the cold weather would interfere with the process, making the concrete set more slowly. That in turn would make the surface application take even more time. There would even be the possibility of the concrete slab crusting, where only its top part sets.

So, if Aquatera’s upgrade was ever going to happen, the company’s construction team would need a non-surface-applied solution that could handle the cold weather just fine.

To Manage These Obstacles, Aquatera Chose Smart Concrete Solutions

The main challenge for Aquatera was eliminating the difficulties that come with surface-applied products. Luckily, they soon came across Kryton’s Edmonton distributor, Cascade Aqua-Tech Ltd. From there, they were able to secure their very own supply of our integral concrete waterproofing admixture, Krystol Internal Membrane

(KIM), and our integral concrete hardening admixture, Hard-Cem

Using the Concrete Admixtures KIM and Hard-Cem, They Were Able to Ease Their Construction Timeline

Because both KIM and Hard-Cem are integral admixtures, they can be added directly into a concrete mix. That eliminates the need to hire extra labor to apply waterproofing and hardening solutions. There’s also little concern for application errors. Instead, each admixture will permeate throughout the concrete, giving it an even, thorough dose of waterproofing and hardening.

The construction team benefited from this approach, adding the products to the concrete mix to meet the specific needs of the wastewater treatment plan.

For KIM, they started by adding it separately to the following:

Some slabs and retaining walls for the gallery and tunnel raftExposed structural concrete that was covering the first two structuresA raft slab and some compartment walls for the BNRs and circular secondary clarifier filters

That allowed KIM to protect each area from potential chemical attacks as the Krystol technology within the admixture could form interlocking crystals that block out water and waterborne particles and fill up any spaces that either might pass through.

For Hard-Cem, they added it separately to the centrifuge building’s slab-on-grade. That would double the building’s resistance to abrasive and erosive wear so that it could withstand the exposure to chlorides and severe amounts of sulfate from the wastewater treatment process.

And for extra protection for the plant’s steel deck, the construction team added both KIM and Hard-Cem to the concrete mix, giving the deck’s surrounding concrete protection against moisture ingress, chemical attack, and abrasive and erosive wear.

Even When Weather Conditions Worsened, Their Construction Still Went By Relatively Smoothly

Because of how easy it was to apply these concrete admixtures, the construction team was able to diligently and effectively continue their work throughout two snowy winters — even when one winter came with a snowfall that was over 10 ft!

Such weather would have made it harder to work with surface-applied concrete waterproofing and hardening solutions as the solutions themselves would have needed protection from the cold.

But with the instant application of concrete admixtures KIM and Hard-Cem, where they can be directly added to the concrete mix during batching, it made it easy for the construction team to both waterproof and harden their concrete. There was no concern over protecting the admixtures after all. The admixtures would simply go into the mix and provide their benefits while the team could carry on with heating the ground and properly placing and curing their concrete.

Overall, KIM and Hard-Cem Transformed Aquatera’s Expansion into a Success 

In the end, thanks to the concrete admixtures, KIM and Hard-Cem, Aquatera’s construction team was able to upgrade the wastewater treatment plant within their timeline. It was a successful bit of construction that was only further proven to be so when the upgrades passed every hydrostatic test the team put them through.

Both KIM and Hard-Cem have gone on to contribute to many other success stories like this one. If you want to see more of their work, take a look at our library of case studies.

This past year, contractors and precast companies throughout North America got a chance to increase their productivity when it came to concrete monitoring. With the 2020 North American launch of Maturix Smart Concrete Sensors, they could now monitor concrete with fully wireless sensors that can be accessed remotely. All of which made monitoring concrete quicker and much more cost-effective.

The sensors caught a lot of industry interest because of this. Of course, that interest didn’t just come from the North American launch. The sensors were initially launched in Denmark and generated a lot of interest before coming to this continent. Since then, 555 Maturix suitcases have been distributed. With their help, builders were able to create 4,248 precast reports and 6,443 in-situ reports. That went on to improve 861 projects in just one year. (To see just how successful these projects have been, take a look at this interview with one of our clients.)

We’re excited to bring MaturixSensors to the North American market and have been fielding a lot of calls from clients interested in the technology. If you happen to be interested yourself and want to know more, we have created an easy-to-read online guide here for you on the most frequently asked questions about Maturix.

First Off, What Is Maturix?

We’ve shared that Maturix is a type of sensor that wirelessly monitors concrete as it develops. But there’s much more to it than that!

To start, the setup is simple. All the Maturix Sensor needs is a connection with a type K thermocouple wire, which is attached to the rebar within concrete. Once connected, the sensor will immediately start monitoring the concrete’s developing temperature and strength. The data it gains from this monitoring is then transferred wirelessly to a cloud-based platform. That platform will go on to send the data to any connected device a user chooses.

In short, Maturix makes fully remote monitoring possible and offers users a way to determine what exact temperature and strength their concrete has at any time. So contractors don’t have to send someone out to physically retrieve the data. And precast companies can remove the guesswork involved in determining when they should remove formwork. That allows them to save time, cut costs, reduce risks, maintain quality control, improve workflow, and more.

How Does It Work?

So, now, we know what it is and what it does.

But how exactly does Maturix work? How is it able to provide such accurate measurements on concrete temperature and strength?

Well, once it’s plugged into a thermocouple wire that’s embedded into a concrete slab, the Maturix Sensor is able to take the actual core temperature of that slab. Then, it can use that information to calculate the compressive strength of the concrete. To do that, it uses a calibrated maturity curve that’s based on ASTM C1074 — Standard Practice for Estimating Concrete Strength by the Maturity Method.

Many in the industry view this method to be one of the more highly accurate and reliable ones out there as the sensor’s thermocouple wire is embedded into the concrete. That gives the sensor a look at the concrete’s actual conditions. In return, construction workers can get a true reading on the status of their concrete on-site. So they can make better building decisions to reduce project risks.

What Makes It Different from Other Concrete Monitoring Devices Out There?

There are a number of differences that set Maturix apart from other sensors. But the most evident is its reusability. Unlike with most other wireless sensors, you can take the Maturix Sensors you used in a previous project and continue using them in future projects. Even if your future project needs to be done in multiple phases, you can still reuse your sensors after each phase, making Maturix highly efficient.

That’s mainly thanks to how these sensors are designed. The sensors themselves remain outside of the concrete in tough, durable cases. That way, they can stay safe while monitoring concrete at the worksite. At the same time, they’re still able to accurately monitor because they’re connected to thermocouple wires that are embedded in the concrete.

Because of that, the type K thermocouple wires themselves become unusable after one project. However, they are pretty easy to find around the world and can be bought for a reasonable price.

In short, you get to save a lot of money on buying sensors for each project while spending just a little bit to replace their thermocouple wires.

If you were to use other sensors, however, you’d likely have to worry about buying a whole new set of them for each project. There are also other disadvantages to consider too. For instance, sensors that use Bluetooth technology often expire after a single use. They also cannot transmit data from too far a distance, meaning users will still need to go to the worksite to access the data.

Temperature data loggers are not much better. They can be reusable. But their data needs to be manually collected and then manually exported and analyzed. There’s no system to do all that work for you. So it falls on your team to spend more time on that.

What about Data Collection? How Does That Work Differently?

When you use Maturix, you’ll find that once activated, it will transmit concrete monitoring data every 10 minutes. During this process, the data will go from the sensor to a cloud-based platform.

How Can I Access the Data through the Maturix Software?

Once your data is stored in the cloud-based platform, you can access it at any time through a browser on any connected device. You can go with any browser, but we recommend using Google Chrome or Mozilla Firefox.

After your user account is set up then, you’ll be able to easily log in to the platform through your preferred browser and access your data. Once there, you’ll be all set to view all the concrete monitoring data you like!

Is There a Limit to the Number of Users Who Can Do the Same?

Not at all! You can invite as many users as you’d like to join your concrete monitoring. That way, you and your team can all see how your concrete develops as it happens in real time.

Is There a Way to Alert Myself and Others to Key Concrete Monitoring Moments?

Yes! Maturix offers an alert system so that the right people are alerted to critical monitoring activities at all times. That ensures everyone gets the right data at the right time, expediting approvals in the process. It also allows you and your team to better prepare for any sudden changes to your concrete’s condition.

Some of the critical activities you can notify yourself and others about include the following:

Concrete temperature going above or below a certain valueTemperature difference, concrete strength, or concrete maturity going above a certain valueA Maturix Sensor not receiving data or being disconnected after a certain time

There’s no limit to how many of these notifications you can create either. So you can add as many or as few as you need to best serve your project.

Is All This Under Warranty?

Yes, these sensors are warrantied for life! All you need to do is maintain your monitoring service subscription, and we’ll continue to provide the best service possible for them.

What If I Have More Questions about Maturix?

This article should give you all the basic information you need to know in order to work with Maturix. But if you still have questions, don’t worry! There are plenty of resources at your disposal. For instance, we have a section on our website that deals with these and other frequently asked questions. You can also contact a representative of ours for a more hands-on approach to learning how to use Maturix.

In short, with Maturix, you not only get the benefits of concrete monitoring data wherever you are, you also get extensive technical support from Kryton.

It’s the beginning of a new year full of possibilities for business leaders. We still face many of the same challenges as last year, but with the rollout of vaccines worldwide, we should start to experience more stability in the market.

However, there’s still a ways to go, so how do we continue to adapt and maximize the opportunities in the year ahead?

We heard a lot about how to pivot our business in 2020. Now, we need to consider what that means to us in 2021. To do that, we should look at what’s affected everyone the most and how we can use it to up our game.

Consider the Rising Adoption of Business Technology

Recent reports have shown that the adoption of technology has increased significantly over previous years, with the use of video conferencing technology on its own rising by 35%.

It was no different for us here at Kryton as virtual meetings became a mainstay for our communication. Despite this change in workflow, our team did a great job in responding to our immediate need to conduct business virtually. We held meetings on Zoom, participated in virtual trade shows, hosted online webinars, and increased our presence on the web through social media posts and digital marketing.

While we personally have managed to step up our game in the digital landscape, I know we have only tapped into a small percentage of what’s available to us in virtual communications. And it’s not about adding more systems to the mix. It’s about fully utilizing the systems we now have in place, ensuring our skills keep up with the technology we have.

Every business leader should consider this because according to the World Economic Forum, the gap between technology and skills is getting so broad that we are in a global crisis. Part of it stems from a common conundrum in business where professionals invest in new systems but struggle with adoption.

If you look at this in the context of my favorite sport, golf, it’s like buying a set of clubs and then hitting the links with no training. You’ll manage to get some decent shots once in a while, but your score will be mediocre at best. To take your game to the next level, you need training and practice.

That May Mean Working with Video Conferencing Technology More Often

With the global workforce moving to a work-from-home model and more meetings being held online, remote tools, like video conferencing, have become an essential component of the modern business world. That hasn’t always been easy for most of us, I imagine. But through trial and error, our team at Kryton has learned some of the best practices that all of us can apply when using video conferencing technology.

To Start, You’ll Want to Mitigate Potential Technical Difficulties

You don’t want to have to delay a meeting with an important client just because your video conferencing system isn’t working properly. Solving technical difficulties can take up valuable time, so it’s best if you make sure the technology can run smoothly before you head to the meeting. That includes checking your Internet connection, software, camera, microphone, and other technical devices for any issues. You’ll also want to log in early, if possible, so you have the time to troubleshoot. It’s especially critical to do that if you’re the host as that ensures your meeting will start on time.

Stay on Mute When You’re Not Talking

Most microphones can pick up minor background noises like typing and coughing. These sounds can easily distract other video conferencing participants and potentially even cause annoyance. So make sure you mute yourself when you’re not taking part in the conversation.

nd Ensure You Treat These Meetings as If You Were There in Person

While it’s easy to get distracted with checking your inbox and browsing online during a video conference, you probably shouldn’t. Treat it as though you are attending a meeting in person. Also, look into the camera instead of the computer monitor when you speak so you appear to be looking directly at the person.

There are many more tips to consider for video conferencing, but the key takeaway is to treat it like it’s a meeting in person. For instance, being on time, dressing properly, and paying attention are all expected for in-person meetings, and it’s no different for remote ones. A good rule of thumb is to ask yourself if you would do the same thing if you were in a physical meeting.

Don’t Let Technical Difficulties Hold You Back

It’s typical for users to only learn as much as it takes to achieve the meeting, but not go on to become proficient with the tool. This can be a big mistake and missed opportunity. I’m encouraging my team to go pro and master the skills needed to fully benefit from these communication tools. And I encourage all business leaders to do the same. Don’t let your technology hold you back or limit you in any way. As a business owner, consider the time and training needed for your employees to learn new systems. Training sessions, peer groups, manuals, and briefing documents can all support the adoption of new technology. As a user, commit to taking the time to practice and learn. This will benefit you now and in the long run as virtual communication becomes a permanent part of the business landscape.

Sustainable architecture and concrete are not always considered compatible. After all, the production of concrete is known as the cause for at least 8% of the world’s carbon emissions. It’s why many concrete producers nowadays are creating their own low-carbon concrete mixes. And it’s also why some architects are hesitant about their use of concrete.

That is especially the case now as the effects of climate change advance. With this progression, people are seeing an increase in severe storms and heat waves. They’re also seeing a significant rise in temperature in the Arctic. It’s warming up two-and-a-half times faster than any other region on the planet. To better visualize this, consider that the New York Times has noted the average air temperatures in 2019 for the world were around 3.5°F (1.9°C) higher than the average temperatures found from 1981–2010. Because of this, the Arctic’s ice is melting away, leaving behind more ocean to absorb sunlight and radiate more heat. All of which heats up the rest of the planet that much more.

In response to this, many architects have felt a stronger need to incorporate sustainability into their work. For instance, a number of architects have chosen to solely work with clients who are aiming to build to net-zero energy standards. Though, not all such sustainability efforts have been this recent in the world of architects. The American Institute of Architects itself has had a commitment to sustainability for as long as 1971. And architects have only been increasing their focus on this commitment to sustainable architecture ever since.

With their concerns over the state of the climate, architects have become a little wary about using concrete. However, concrete remains an incredibly common building material. And there’s good reason for that. Whatever you think of it personally, concrete has much to offer sustainable architecture!

For One, Concrete Can Create One of the Most Energy-Efficient Walls Available

Known as insulated concrete form (ICF) walls, these structures are considered to be one of the most energy-efficient forms available. In fact, according to Concrete Construction, back in 2009, ICF walls were what gave Beverly Stevenart, the co-owner of Craftsman Homes & Design, in Colorado from the United States of America (USA), a way to construct a net-zero energy home. They’re also a form that the New York City-based Curtis + Ginsberg Architects have frequently used over the years to great effect in a number of projects. These include the Calvert Lancaster building on Lexington Avenue, which earned a silver certification in the Leadership in Energy and Environmental Design (LEED) program. They’ve also achieved multiple other LEED and passive house certifications with their ICF construction.

ICFs have not just been benefitting sustainable architecture in the USA, though. While places outside North America focus a little less on ICF construction, it still plays a big part in Europe and is gaining traction in regions like Asia, South America, and the Middle East.

But how does it work?

Well, let’s look at how ICFs are made first. At the start, they’re molded from either expanded or extruded polystyrene. This mold then typically takes on the form of lightweight open-cell concrete blocks or panels. These then act as the forms for poured concrete (which can be for above or below grade walls). The end result is a number of walls that combine the benefits of concrete and integral insulation. From concrete, the walls gain a decent amount of thermal mass and strength. And from the integral insulation, the walls receive a number of energy-saving benefits. All of which makes them highly energy efficient and even more thermally efficient than traditional wood-framed assemblies.

These Happen to Manage Temperature Well and in Different Climates

That is great news for architects looking to cut down on energy loss for their sustainable architecture. With the thermal efficiency of ICF exterior walls, they can create a design that uses less energy to cool down and warm up compared to wood-framed houses. Based on estimates from the home performance magazine Home Energy, that equates to ICF exterior walls cooling down with around 32% less energy and warming up with 44% less energy than a wood-framed house would. The estimated savings for this amounted to an average of $200 a year.

Of course, the average energy saved in all this does depend a bit on the surrounding climate. For colder areas in North America, the buildings might save more on heating than cooling. The reverse can be said for warmer areas.

Still, no matter the climate, the ICF walls will still provide energy savings. To confirm this and compare the performance to code-matching and wood-framed homes, the Portland Cement Association (PCA) conducted a study. For this study, they looked at the performance of homes in several cities across the USA. These were Chicago, Miami, Phoenix, Seattle, and Washington D.C. After observing each location, the PCA noted that the homes with ICF walls saved significantly on energy. Compared to code-matching homes, the ICF-constructed ones used 8% to 19% less energy. And compared to wood-framed homes, they used 5% to 9% less energy. On top of that, they even exceeded the requirements from the International Energy Conservation Code.

What’s more, ICF walls can also absorb the temperature swings of any climate. This is mainly thanks to their concrete thermal mass, which allows them to absorb heat. In turn, this heat can help them regulate the internal temperature of a building. So, for instance, if the building is in a desert, its ICF walls will absorb the day’s heat. Then, by the time it becomes freezing at night, the heat from the concrete will still keep the interior’s temperature relatively warm and stable.

nd They Provide a Tight Design That Allows for More Cost-Effective HVAC Systems

ICF walls aren’t just great for dealing with energy loss and temperatures. They also provide a tighter fitting design, which works well for energy efficiency in other areas. One area in particular is structural leaks. With the tight design of ICF walls, there’s less room for air leakages and outside air infiltration. Confirming this fact, one PCA study noted that ICF walls had an air leakage rate of 0.15 air changes per hour, while wood-framed homes had 0.78 air changes per hour.

To add to that, the design of ICF walls allow for smaller and more affordable HVAC systems. Because ICF construction doesn’t need as much HVAC energy, construction teams can choose a more compact and affordable setup. That also allows them to save around $500–$2,000 per home while still supporting sustainable architecture.

Those Aren’t the Only Benefits They Provide Either

They also come with the following advantages for sustainable architecture over other walls like wood-framed ones:

Better fire resistance — According to research done by the U.S. Department of Housing and Urban Development, ICF walls offer some of the best fire resistance available. For instance, they can endure fires at extreme levels for up to four hours, while wood-framed walls generally do not last more than a one-hour fire rating. This is because concrete is not an organic material that would fuel a fire. So unlike wood, which can contribute to fire growth, concrete can avoid exacerbating it while resisting damage at the same time.

Increased durability — Known to be a long-lasting material, concrete has gotten this reputation due to its ability to resist wear and tear, severe weather, rot, insects, and fire. And the ICF walls that concrete can create can do the same while also resisting moisture. Likewise, wood-framed walls can have a similar form of resistance from environmental factors when placed in the interior of a building. However, as the U.S. Department of Housing and Urban Development notes, they are still vulnerable to rotting if water manages to get into the building. They’re also vulnerable to termite attacks, which can cause a fair bit of structural damage.

Stronger noise control — The publication Construction Canada suggests that ICF walls may even provide up to 40% lower sound transmission compared to wood-framed walls. Backing up that idea, the U.S. Department of Housing and Urban Development’s study states that a typical wood wall may have a sound transmission class (STC) rating of 35 to 49, while ICF walls will have a rating of 48 to 58. So the sound of shouting could likely be heard through the wood-framed walls, but less so for ICF walls. Of course, there is also the option of using enhanced wood walls as well, which doesn’t quite reach the STC ratings of ICF walls. But it gets pretty close, hitting the 50 to 54 STC rating. Still, for the best noise control, ICF walls offer the better bet.

Fewer potential insurance concerns — Depending on the region, building owners may also deal with fewer insurance concerns if their structure uses concrete materials. In Vancouver, Canada, for example, GLOBE Advisors underwent research to compare the insurance costs between mid-rise wood-framed buildings and concrete residential buildings. The end results of that research showed that while there is a risk of water damage to concrete buildings, generally that damage is easier to find and resolve compared to the damage found in mid-rise wood-framed buildings. With wood construction, moisture concerns are harder to detect so they can fester for years, and if they’re not found in time, they can render a building uninhabitable. Additionally, wood-framed buildings come with a higher risk of fire and mold compared to concrete buildings. All of which can lead to higher insurance rates as insurance companies want to deal with as little risk as possible.

Of Course, Concrete on Its Own Has a Number of Sustainable Traits

Concrete isn’t just a way for architects to build energy-efficient ICF walls with benefits. It’s also a material that comes with its own sustainable traits.

For One, It’s Quite Versatile, Allowing It to Fulfill a Variety of Design Needs

With this versatile nature, concrete makes a project design that much easier to complete. It allows builders to choose what type of consistency it’ll have, how it’ll flow, what setting times it’ll have, and which hardened properties it’ll use.

They can even affect each of these aspects while adding beneficial qualities through the use of admixtures.  So if they want to avoid petroleum-based waterproofing membranes, they can directly add an admixture like the Krystol Internal Membrane

(KIM to a concrete mix. That allows them to make the concrete inherently and permanently waterproof without the need for toxic elements or volatile organic compounds (VOCs). KIM will also protect the reinforcement from corrosion, which can extend the structure’s life cycle and reduce future maintenance expenses.

The same goes for when they want to enhance the concrete’s durability against abrasion. They can replace dry shake hardeners and sealers, which can expose workers to silica dust and VOCs, with the durability admixture Hard-Cem. Adding it directly to a concrete mix gives the concrete a high resistance to both abrasion and erosion, doubling its life span.

All of which makes it possible to use concrete in a wide variety of applications while ensuring the structures they form remain functional now and in the future. After all, concrete represents an investment, and it is critical to ensure that investment will last. Admixtures make this possible while adding more benefits and reducing the amount of carbon pollutants that are emitted throughout the building’s life cycle.

On Top of That, Concrete Is Reusable

Even if a concrete project is eventually set for demolition, it is still possible to reuse it! That remains the case even if the concrete has rebar within it. That’s because workers can separate the rebar from the concrete with large magnets to be reused for future projects. And they can then crush the concrete into fragments of varying sizes. These fragments can then help create the following:

Pavement for walkways and drivewaysBed foundation material for trenchesLandscaping mulchFill for wire cagesOceanic reef habitats

Most significantly, though, they can act as replacement for aggregate in concrete mixes. That helps builders reduce the amount of gravel and sand extraction needed. And that in turn is better for sustainability as it lowers the amount of resource extraction that occurs in construction.

Of course, it’s important to note that this sort of reusability only works for concrete with no contaminating substances. After all, concrete with calcium sulfate, chlorides, oils, or surface-applied membranes can render the concrete unsuitable for reuse, meaning it ends up in a landfill.

But concrete without those concerns, from start to finish, can be a great ally to sustainable architecture. While it can also be a carbon-intensive material, the construction industry has been hard at work producing better alternatives. From that mindset, we’ve come up with energy-efficient ICF walls, admixtures that reduce carbon emissions, and ways to reuse concrete. So for worried architects, using concrete does not have to be a cause for concern. In fact, it could aid you in your design for a greener, more sustainable building.
