Abstract

In this paper, we researched and compared the properties of steel slag(is divided with electric arc furnace slag and converter slag) as concrete aggregate by measuring physical and chemical characteristics of it. The steel slag mainly contains SiO2 and CaO as the chemical composition. The reaction with water and a little of free CaO in the slag causes slag's volume to expanse. Therefore, we used several aging methods in order to decrease the characteristics of slag volume expansion. The physical properties of steel slag aggregate is researched and then the strength of concrete with the steel slag aggregate is measured.
