Read more +This paper aims to study the effect of cyclic heating and flowing-watercoolingconditions on the physical properties of granite. Ultrasonic tests, gas measured porosity, permeability, and microscope observations were conducted on granite after thermal treatment. The results showed that the velocity of P- and S-waves decreased as the number of thermalcyclesincreased.
