Applicability of Induction Furnace Steel Slag in RC Columns Subjected to Axial and Uniaxial Loading

Abstract

Carbon emissions and sand mining have generated massive environmental imbalances. Because of the impact of depleting resources, using slag in concrete is a viable alternative for minimizing environmental impact. The acceptability of using induction furnace steel slag as a partial replacement for aggregate and as an additive in concrete mixtures for columns was investigated. Ten 140 mm × 140 mm × 750 mm short columns subjected to axial and uniaxial loads were tested. The outcome demonstrates that using SS in general decreases displacement levels and increases load levels. The proposed steel slag as a 30 % sand replacement mixture is preferred over the others. All the suggested combinations showed decreases in the ductility ratio and energy absorption. Induction furnace steel slag can be used in concrete columns.
