In India, many talks are being heard about sustainable construction and researchers are taking up studies here and there on use of unconventional construction materials that are aimed in using waste materials. However, focused attention on sustainability of materials for construction is needed. Though the time is not yet ripe for forming such an association in India, it is time for everyone concerned in the topic to start thinking about such a move. So here in this research main concern on the reuse of construction and demolition waste in Self Compacting Concrete. In this research we use recycled coarse aggregate as well as recycled fine aggregate with replacement of natural aggregates. As per previous records there is considerably decrement in the strength property by using these kinds of recycled materials. This happen due to lower quality of recycled aggregates to improve the quality of R.A. here we apply cement slurry treatment on the R.A. and use this Processed Recycled Aggregates (PRA) with fine recycled aggregates (FRA). In this research we replaced 10, 20, 30% RA with natural aggregates. Then we replaced PRA 10, 20 and 30% with N.A. Also we combine proportion of PRA and FRA and measure compressive, tensile and flexural strength of concrete. Also we measure workability and compaction factor for all the mix. In the mix design we used 0.57 W/C because there is higher water absorption of R.A. At the end we also compare the cost of RAC and NAC as well as PRAC, RAC and NAC. R.F.A.combined it with processed R.C.A. to reduce the overall cost of concrete.

Keywords- Natural Coarse Aggregates (NCA), Recycled Coarse Aggregates (RCA), Recycled Aggregates Concrete (RAC), Processed Recycled Aggregate Concrete (PRAC) Processed Recycled aggregates (PRA) Self Compacting Concrete (SCC).
