Abstract

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 and dry seasons. During the process, GPR measurements were carried out periodically to monitor signal changes. The results were analyzed to study the GPR signal amplitude, travel time, frequency spectrum and signal energy response to chloride contamination and reinforcing steel corrosion in concrete.
