This research is a fundamental experiment as an attempt to establishment of a non-destructive method by using the remote sensing technique for concrete structures. In this experiment the heat conductivity of concrete was compared based on the water-cement ratio of concrete and also on the elapse of time(to compare wet and dry conditions). Secondly a cylindrical mortar and concrete specimens were tested by using a compression machine in order to study the relation between axial stress and the surface temperature of the specimen. It was found that the patterns of heat conductivity based on the water-cement ratio of specimens are separated. The heating phenomenon of surface temperature of the tested specimens under the axial stress condition was also cleared to be the same as KAISER effect.
