The focus of this study is to determine the structural performance of optimum mix of recycled coarse aggregate concrete by different curing regimes and to compare the recycled aggregate concrete with conventional concrete. The curing condition used in this study are normal curing and use of two type of self-curing agent i.e., poly ethylene glycol 4000 and paraffin wax. The control mix used in this study is M25 with addition of 10% of metakaolin. The percentage of recycled aggregate is varying 0%-60%. The properties of recycled aggregate are improved by using surface treatment (HCl treatment). © IAEME Publication.
