Properties of concrete having treated recycled coarse aggregate and slag

The possibility of using substitute materials for aggregates and cement in concrete were studied reported this paper. Concrete mixtures with untreated recycled coarse (URCA) treated (TRCA) used to prepare two mix groups without slag (Mix I) II). hydrochloric acid (HCl) having different molarities (0.1M, 0.3M 0.5M) before as a material virgin aggregate concrete. mechanical, durability properties morphology examined through standard experiments analysed. In both considerable improvement all characteristics identified TRCA mixes than URCA mixes. Among the II) showed better I). combination substantially increases means.
