Abstract
The present study is aimed to study the effect of elevated temperatures ranging from 50 to 250°C on the compressive strength of high-strength concrete (HSC) of M60 grade made with ordinary portland cement (OPC) and pozzolona Portland cement (PPC). Tests were conducted on 100 mm cube specimens. The specimens were heated to different temperatures of 50, 100, 150, 200 and 250°C for three different exposure durations of 1, 2 and 3 h at each temperature. The rate of heating was maintained as per ISO-834 temperature–time curve for standard fire. After the heat treatment, the specimens were tested for compressive strengths. Test results were analysed and the effects of elevated temperatures on PPC concrete were compared with OPC concrete. The PPC concrete exhibited better performance than OPC concrete.
