In this episode of Concrete Logic, we welcome Mark Chase of RPX Technologies to the show. Mark is an expert on concrete sensors. These sensors are used to monitor the strength and temperature of in-place concrete. Traditionally during construction, the strength of concrete placed in a structure is determined by breaking a 6" x 12" (or 4" x 8") concrete cylinder sample taken during the placement. Mark and I discuss the downfalls of this archaic process and how monitoring the temperature of the concrete that is actually placed may be a better (and safer) strategy for your next project.
