Effects of Sustained Elevated Temperature on Concrete Properties in Material Engineering and its Applications

Article Preview

This paper presents the results of experiment conducted to evaluate the effects of sustained elevated temperature on concrete. In this experiment, concrete with 4 types of cement, low-heat portland cement, blast-furnace slag cement and fly-ash cement were tested for strength without seal after sustained temperature exposure in the range of 20 to 300°C. Compressive strengths did not decline linearly with temperature and were minimal at around 50°C, showing 20% reduction, which associated with inter-mediate weight loss of 3%. Reductions in tensile strength and modulus of elasticity were greater than compressive strength.
