Reducing the Risk of Hot Weather Concreting with Maturix® Sensors

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.
