Parametric Study of Steel Slag Powder as Cementitious Material on Cement Mortars

摘要

Steel slag (basic oxygen furnace slag) is a by-product left over from the conversion of iron to steel in steel industries. Currently in India, steel slag is being used as replacement of loose aggregate for road construction. Due to its ever increasing production and hazardous effects due to dumping of slag there is a need to study its effect on mortar and concrete with higher replacement ratios. 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. The results showed that the preferred content of steel slag powder as replacement of OPC was 20%. Additionally, this research will contribute to our understanding of how to sustainably manage industrial wastes with economical and environmental benefits.
