The construction surface temperature rises in the defect portion as compared with the sound portion in daytime when the void by concrete exfoliation exists in the construction. The detection of the exfoliation becomes possible by sensing this temperature distribution in the thermal image. However, inspecting concrete exfoliation with thermal image is greatly influenced by environmental conditions of sunshiny and temperature, etc. Moreover, there will be improper time zone in the observation in a day, and the time zone is also different depending on an environmental condition. Therefore, the thermal image observation in the field and numerical analysis by the heat balance model were done to verify whether concrete exfoliation was able to be distinguished in case of what condition be it, and the use condition was made a fixed quantity.
