This paper focuses on effect of elevated temperature on recycled aggregate concrete. When concrete is exposed to Elevated Temperature due to fire, the property of a concrete may alters. The effects of elevated temperatures on the physical and mechanical properties of various Recycled aggregate concretes are explained Here w/c ratio 0.27 and 0.36 with replacement of 0%, 30%, 35%, 40%, 45% and 50% of Natural aggregates by Recycled aggregates are taken into consideration. Here 35 specimens (Cubes, Cylinder and prism) for each trial mixes (12 nos) has been casted and heated under four different temperature: 200 0 C, 400 0 C, 600 0 C and 800°C.. Attempt is made to compare with different mixes of recycled aggregate concrete. The results indicate that concrete with aggregate partially replaced with RCA exhibits good performance under elevated temperatures and it can be considered comparable to conventional concrete.
