Abstract
Samples (two granites, marble, sandstone) were heated in an electric furnace at temperature $400^{\circ}C$ and $600^{\circ}C$ in order to investigate the change of physical properties of rocks depending on the heating temperature. Changes of Color and physical properties such as specify gravity, porosity, absorption, p-wave velocity are visible while mineralogical changes by using polarizing microscope are not pronounced. In addition, porosity and absorption increased while specific gravity and p-wave velocity decreased at a more higher temperature ($600^{\circ}C$). Although the open porosity does not indicate total porosity of the rock. but p-wave velocity can be used to evaluate the degree of damage Therefore, porosity and p-wave velocity should be compared in order to investigate the change of physical properties of rocks depending on the heating temperature.
