Effect of Elevated Temperatures on Conventional Concrete

Abstract

Under elevated temperatures, concrete will not burn and it also will not emit any flume but there will lose its strength as temperature increases, in the presented experimental investigations, the effect of increase in temperatures on properties of concrete was done. Strength of concrete like compressive strength, split tensile strength, flexural strength was determined at 28 days. The concrete cubes, beams and cylinders samples were heated at controlled temperatures at 200, 400, 600, 800, 1000 ℃ for 0.5, 1 and 1.5 h and tested after 0.5 h of natural cooling. At enhanced temperature, strength of concrete and weight continuously reduces as the temperature was increasing, strength of concrete and weight of concrete reduced up to 70% and 14% at elevated temperatures, respectively.
