Here’s a step-by-step guide to estimating concrete strength using COMMAND Center concrete temperature and maturity sensors:

Step 1: Build the Maturity Curve:

A maturity curve is a graphical representation of the relationship between concrete strength and maturity. To build the curve, maturity sensors are inserted in concrete beams and columns using a mix that is as close as possible to the concrete to be used during construction. Use a compatible COMMAND Center reader to collect the sensor data and COMMAND Center software will guide you through generating a curve by automatically correlating the maturity data to your test specimen breaks. There are a number of ways to plot the data and COMMAND Center allows you to use multiple curve-fitting techniques. Most specifications provide a curve-fitting technique.

It’s important in this step to batch and test concrete that will be as close as possible to the concrete used during construction. This includes batch size, mixing equipment, mix proportions, material sources and manufacturers. Any deviations in concrete preparation will reduce the quality of strength estimates from the maturity curve.
