The chemical composition of steel slag showed potential for use as cementitious component. This paper explores the use of partially replacing cement with locally available steel slag for making of cement mortar. The effects of steel slag powder on the normal consistency water requirement, setting times, compressive strength were studied.

2020-5-22 Furthermore, steel slag's resistance to polishing means that it's frictional benefits are maintained over time. Cement production is another area where steel slag has proven especially beneficial over other aggregates. Steel slag undergoes calcination during it's production which removes most volatile materials and CO2.

Production of slag cement creates a value-added product from a material—blast furnace slag—that otherwise might be destined for disposal. The manufacture of slag cement not only lessens the burden on landfills, but also reduces air emissions at steel plants through the granulation process (as compared to the traditional air-cooling process).

2019-3-1 Steel slag is a solid waste produced by extracting impurities with lime during steelmaking, and the discharge is about 10% to 15% of steel production. The characteristics of the steel slag itself, such as hydraulic hardness and wear resistance, give the steel slag aggregate a characteristic that is not possessed by a series of natural aggregates.
