| Research Abstract |
This study aimed at developing a new non-destructive test method using induction heating (IH) and infrared thermography for quantitative assessment of rebar corrosion. Rebars under cover concrete were heated with an IH device, and the effects of rebar diameter and corrosion amount on the temperature distribution on the cover concrete surface were investigated using an infrared thermography camera. A larger corrosion amount suppressed heat diffusion from the rebars to the cover concrete and reduced the increase in surface temperature of the cover concrete.
