Abstract: All over the world, wide amount of demolishing waste is being generated posing lot of environmental issues. To address these issues, Self-Compacting Concrete (SCC) was made by replacing cement partially with mineral admixtures and NCA with RCA. The fresh and hardened properties for M30 grade of SCC made with NCA and RCA were evaluated. Cement in SCC was recouped partly with 30% Fly Ash, 20% GGBS by weight of the cement. Polypropylene fibers at 0.1% were added to study their influencing nature on the hardened state and fresh state properties of the SCC mix. Four sequences of SCC mixes of M30 were prepared by substituting the NCA with RCA at 25%, 50%, 75% and 100% derived from the dismantled concrete waste of M30 parent grade. SCC produced with the RCA up to 50% and with 0.1% addition of Fibers demonstrated comparable performance as that of SCC with NCA.
