Cementitious properties of super-fine steel slag

Powder Technology, 2013
Abstract In this study, a super-fine steel slag with the specific surface area of 786 m2/kg was prepared by mechanical grinding. Its cementitious properties were investigated by comparing the results obtained from it with those obtained from ordinary steel slag, fly ash, and cement.
