Abstract: The present study looked at the damage characteristics and thermophysical properties of limestone and sandstone at -30 to 1000 °C. A Hot Disk TPS 2500S thermal constants analyzer was used to measure thermal conductivity, thermal diffusivity, and specific heat of the rock samples. Results showed that water migration and phase transition were two core factors for thermal behaviors. Thermal conductivity and thermal diffusivity were found to decrease during the heating process, while specific heat capacity increased.
