Abstract: The use of recycled aggregate in any concrete saves the virgin coarse and fine aggregates to create for the production of concrete. This concept will deliver an ecofriendly, reduced eviction of natural resources and produce a green concrete concept. Coarse aggregate consists of more than 60% of total volume in ordinary concrete but only 40% is required for Self Compacting Concrete (SCC) by weight. Demolished concrete wastes which are crushed and sieved to the size are used as substitute for natural coarse aggregates. In this paper natural coarse aggregate in self-compacting concrete is replaced with 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% & 100% recycled aggregates in mix design. Furthermore, a detailed study on workability and hardened properties of specially proportioned mixes are also carried out and satisfactory results are obtained. Thus the derived SCC can come up with reduced CO2 emissions, economical and energy saving with all additional well-known advantages of fluid concrete.
