This study investigates the effect of chloride contamination and reinforcing steel corrosion in a concrete slab on the ground penetrating radar (GPR) signal. A reinforced concrete slab with two layers of steel bars and chloride contamination was used in this study. The corrosion process was accelerated by impressed current technique in both wet and dry condition to simulate the corrosion in both wet...
This paper presents a new approach to evaluate corrosion of reinforcement in concrete by ground penetrating radar (GPR). Pulse GPRs were used to monitor the continuous corrosion process in concrete, in which the changes of amplitudes, travel times and short time fourier transform (STFT) spectrograms associated with the bar reflections were continuously measured. The yearly long corrosion process of...
