This paper describes the process which deals with the effect of replacing natural coarse aggregate by
recycled aggregate which is carried out by processing field demolished concrete. The natural coarse aggregate (NA) in
concrete was replaced by recycled coarse aggregate (RA) at different percentages such as 20%, 40%, 60%, 80%, 100%
by weight of aggregate of M20 concrete & the compressive test is carried out. Test results showed that the compressive
strength of recycled concrete up to 80% coarse aggregate replacement (C. A. R.) by demolished waste at the end of 28
days has been found to be comparable to the conventional concrete. The result of the study concludes that, the strength of
concrete from recycled aggregates decreases on replacement of RA with NA.
