Abstract

Steel slag, which has low CaO content, is a by-product of steel processing. The steel slag consisting iron oxides is ground into sizes as coarse aggregates used for concrete. In this paper, the steel slag was characterized by chemical, physical and mineralogical analysis, and then the steel slag was used to replace 100% coarse aggregates in high strength concrete which has various compressive strengths as 60, 70 and 80MPa. Results showed that the strength of the concrete using steel slag aggregate was equivalent to that of the conventional concrete, whereas, the durability of the steel slag aggregate concrete was better than that of the conventional concrete in terms of chloride penetration resistance and resistivity. Moreover, dimensional stability of the steel slag cement mortar was detected.
