Abstract

In this study, a new non-destructive testing method for the detailed estimation of the rebar corrosion in RC structure, is proposed using infrare thermography and electromagnetic heating. The corrosion product has insulation effectiveness by heat characteristic. Therefore, when the rebars are heated equally, the surface temperature of concrete in which rebar corroded is lower than that of the concrete in which rebar doesn’t corroded. The result of our experiment shows that it is feasible to use the proposed method.
