TDR Concrete Cure Monitoring

Material Sensing & Instrumentation (MSI)

MSI Time-Domain-Reflectometry (TDR) Concrete Cure Monitoring provides a new approach to cure monitoring in concrete and cementitious materials [1-7]. Using an ultrafast pulse and inexpensive capacitance sensor, our TDR system follows rotation of individual chemical states of water participating in the hydration reaction. The system monitors formation of bound-water hydration products, as well as unreacted free-water to form the hydrated state.
