Non-Destructive Evaluation of Concrete Structures by Non-Stationary Thermal Wave Imaging

Reinforced concrete structures (RCS) have potential application in civil engineering and with the advent of nuclear engineering RCS to be capable enough to withstanding a variety of adverse environmental conditions.However, failures/loss of durability of designed structures due to premature reinforcement corrosion of rebar is a major constrain.Growing concern of safety of structure due to pre-mature deterioration has led to a great demand for development of non-destructive and non-contact testing techniques for monitoring and assessing health of RCS.This paper presents an experimental investigation of rebar corrosion by non-stationary thermal wave imaging.Experimental results have been proven, proposed approach is an effective technique for identification of corrosion in rebar in the concrete samples.
