Hydration of concrete is a very complicated and multiphase process, where the cement gel transforms into a hardened plastic/semi-plastic phase. Proper progression of the hydration process ensures the development of targeted mechanical properties. This project The proposed configuration consists of a thin metal foil instrumented with piezoelectric ceramic (PZT) patch at the free end with the other end of the foil embedded inside the concrete. The sensing capability of the proposed metal foil configuration is evident from the coupled admittance signature quantitatively vis-à-vis the other configurations.
