Use of capacitive and GPR techniques for the non-destructive evaluation of cover concrete

Two non-destructive techniques, namely ground penetrating radar (GPR) and a more original approach based on capacitive measurement, have been considered in this research project that focuses on the evaluation of cover concrete moisture content. Following a numerical modeling step for the capacitive technique, the two methods were successfully compared during an experimental campaign conducted in the laboratory against several control test slabs.
