Construction and Demolition Waste were normally disposed into landfills and in low lying areas and seems to be gradually engaged in construction. According to various researchers, it has been suggested that 90% of the C&DW composition can be recycled and reused as secondary materials. The purpose of this paper is to highlights the performance of C&D based recycled aggregate in SCC to enhance waste management on construction sites. The experimental study conducted with recycled coarse aggregate from C&D concrete waste as an effective replacement for regular coarse aggregate in SCC and the results compared to mix controls. Initially determine the physical properties of materials used in concrete mixture. Later Investigate the appropriate workability and resistance to segregation, passing capacity and filling capacity have been demonstrated by slump flow test, L box test and sieve segregation test. Finally, determine the mechanical properties are such as compressive, split tensile and flexural strength. The result shows that through incorporating the use of recycled aggregate fresh properties with or without recycled, aggregate is nearly identical, but the mechanical properties were minimized due to poor adhesion between the old mortar and the aggregate. So, it was concluded that the 50% of RCA replacement would be better strength of SCC mix and was used for different constructive elements. These findings open-up the possibility of using RCA in SCC preparation in an area where the natural aggregate is rare and expensive. The use of recycled aggregate will achieve cost reductions and environmentally friendly.
