This study investigates the effect of elevated temperatures on the pore structure of cement paste which, in turn, can provides information to evaluate the damage level of concrete structures due to fire. Mercury intrusion porosimetry (MIP) test was conducted for this investigation. Test results showed that the higher the temperature, the higher is the pore volume of cement paste and the wider is the pore distribution.
