Abstract

A new Nondestructive evaluation for internal defects in reinforced concrete is developed by employing thermography and heat charge due to electromagnetic inductance. A target of research is to identify defects existed in concrete cover Nondestructively. Because reinforcing steel-bar should be heated by electromagnetic induction, the effect of induction coil on uniform heating of rebar is first clarified. Based on findings, model specimens with artificial defects are tested. Thus, applicability and limitation of the proposed technique are demonstrated.
