Article Experimental study of concrete using recycled

The RCA was obtained from construction and demolition waste (C&DW) and used as full replacement of natural coarse aggregate (NCA) for production of RAC. Crushed granite was used as NCA, while crushed concrete rubble from a demolished concrete building was used as RCA. Two groups of concrete mixtures were tested NCA as control and RCA.
