Why use concrete sensors for cold weather concreting
According to the American Concrete Institute, Cold Weather Concreting requires special practices to prevent damage to concrete due to freezing at early ages;
Concrete placed during cold weather will develop sufficient strength and durability to satisfy intended service requirements when properly proportioned, produced, placed, and protected.
You can obtain excellent concrete casting in cold weather when the concrete is secured against damages because of early frost and temperature stresses and when the concrete curing process is managed and under control before, during and after casting.
Benefits of using concrete sensors for cold weather concreting
Of course, some costs will be added to enable a safe winter casting and prevent you from taking any additional risk when doing winter concreting. But the cost of taking the required precautions shouldn’t be high compared to the risk of the additional cost of damages and unexpected delays.
Temperature monitoring with sensors
Monitoring the concrete temperature development inside the structure and following the temperature distribution in, e.g. cross-sections provides you with insights: You can see if your precautions are correct or need to be adjusted. Following your simulations’ differences between the real and the expected temperature curve supports your decision-making. Suppose you have done a reliable calibration of the maturity-strength relation for your specific concrete mix design. In that case, you can take decisions and actions based upon the data from the measurements inside the concrete structures.
