Effect of cooling regimes on compressive strength of concrete with lightweight aggregate exposed to high temperature

Abstract In this study, the residual compressive strength of concrete with expanded perlite aggregate (EPA) and pumice aggregate (PA) after it was exposed 700 °C and then cooled in three cooling regimes (natural, water and furnace cooling) at w/b ratio for 0.25, 0.30, 0.35 was investigated. EPA and PA replacements of fine aggregate were used 10%, 20%, and 30%. Test results showed that the compressive strength of concrete cooled in water cooling after being exposed to the effect of different mixture with EPA and PA is higher than that cooled in natural and furnace. Based on the test results, the compressive strength of concrete cooled in water, furnace and natural cooling decreased by an average of 78%, 81% and 83%, respectively, when compared to control samples.
