Abstract
Experimental studies were carried out so as to estimate the influences of temperature and moisture migration on properties of concrete subjected to elevated temperatures. The test pieces were either sealed (up to 175℃) and unsealed (up to 600℃) during temperature exposure, mechanical and thermal properties were studied. The simulated mass concrete mock-up specimens were heated at one side, with maximum temperatures up to 600℃. After heating, the influences of temperature and moisture content on mechanical properties were studied. As a result.it is confirmed that the properties of concrete, subjected to elevated temperatures can be influenced signifficantly by moisture migration during heating.
