Characterization of ground penetrating radar signal during simulated corrosion of concrete reinforcement
In this paper, the adequacy of the experimental design in the accelerated corrosion process with the impressed current technique (IC) for ground penetrating radar (GPR) inspection was investigated. The aim of the study is to observe how the GPR signal amplitude behaves under different distributions of corrosion products generated by different exposure conditions in the IC technique. To investigate this, two different experimental setups were prepared. The results are summarized, discussed, and supported by visual evidence, other non-destructive techniques, and electromagnetic theory. The main finding is that the position of the sodium chloride solution required to ensure accelerated corrosion of the reinforcement determines the behaviour of the GPR signal, as it affects the position of the corrosion product layer and its distribution in the concrete cover.
