This paper presents the influence of different amounts of recycled coarse aggregate (RCA) obtained from a demolished building on the properties of self-compacting concrete (SCC) and compared the results with self- compacting concrete (SCC) containing 100% natural coarse aggregate (NCA). Important properties such as physical and mechanical properties of natural and recycled aggregates are carried out. NCA is partially replaced with RCA by an amount 5%,10%,15%, 20%,25%, 30%,35% and 40%. The effect of RCA on the properties of SCC in green state (e.g. Slump flow test, V-Funnel test and L-Box Test) and properties of concrete in hardened state (e.g. compressive strength, flexural strength, and Split tensile Strength) are studied. The mix design was carried out for M30 grade of concrete. The present study recommends SCC marginally achieves required compressive strength up to 40% replacement of RCA. This paper is to study the effect of utilizing recycled coarse aggregate as partial replacement for natural coarse aggregate on the properties of SCC in fresh and hardened state.
