This Report represents that the influence of varying amounts of recycled coarse aggregate (RCA) collect from a demolished Cancer Hospital, Located at Rajkot, Gujarat, about 50 years old on the properties of self-compacting concrete (SCC) and compared it with the results with normal vibrated concrete (NVC) containing 100% natural coarse aggregate (NCA).The properties such as physical and mechanical properties of natural and recycled coarse aggregates are carried out. NCA is partially replaced with RCA by an amount 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45% and 50%. 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 M-30 and M-35 grade of concrete. The experimental results shows that the compressive strength, flexural strength and split tensile strength is higher than the use of Recycled coarse aggregate and the strength of SCC decreases with an increase rate of replacement percentage of recycled aggregate (RA). The present study recommends SCC marginally achieves required compressive strength up to 40% replacement of RCA.
