In this study, physical and mechanical properties of six carbonate rocks (two marbles, two low-porous limestones and two high-porous limestones) were studied under the influence of temperatures ranging from 105 to 600 A degrees C. It was found that the values of bulk density, P wave velocity, uniaxial compressive strength, modulus of elasticity, Brazilian tensile strength and Shore hardness decreased to different extent, whilst apparent porosity increased under the influence of heat up to 600 A degrees C. The results indicated a maximum decrease of 62-82 % in modulus of elasticity and the least reduction of 1.2-2.7 % in bulk density of carbonate rocks. Moreover, the uniaxial compressive strength, Brazilian tensile strength, P wave velocity and Shore hardness values decreased by 27-51, 28-75, 36-69 and 10-40 %, respectively. Moreover, increase in apparent porosity values of tested rocks with very high porosity was the least, whereas the apparent porosity values of low-porous rocks increased up to ten times of initial value.
