This study aims at experimentally clarifying relationship between mechanical property and damage in concrete exposed to high temperature and low humidity environment. The degree of damage in concrete is evaluated in terms of mercury intrusion porosimetry (MIP) and X-ray radiography, which potentially quantify micro-crack nucleation. In experiment, concrete was exposed to environments in combination of three temperature levels (20, 50, and 70 degree), and three relative humidity levels (30, 60, and 100%). After this exposure, mechanical properties and micro-crack nucleation degree in concrete were measured in comparison with non-exposed concrete in reference. As a result, mechanical properties were decreased by 20% at most. Finally it was found that test results both in MIP and X-ray radiography successfully correlate damage degree in concrete and mechanical property variation.
