N2 - This study introduced both steel slag and recycled aggregate aiming to improve the sustainability performance of self-compacting concrete (SCC). The study focused on investigating the effects of steel slag powder on the properties of self-compacting concrete with recycled aggregate (SCRAC). Recycled aggregates were used to replace 30% of natural coarse aggregates by volume. The effects of various replacement ratios of steel slag powder (SSP) to Portland cement (i.e., 10%, 20%, 30%, 40%, and 50%) on the workability, mechanical properties, and durability of SCRAC were studied. The results showed that SSP improved filling ability and passing ability of SCC, but adversely affected the segregation resistance. It was found that 10% replacement ratio of SSP to ordinary Portland cement (OPC) in SCRAC showed superior mechanical properties and higher durability performance in resisting chloride penetration and carbonation.
