Investigation of Fresh and Hardened Properties of Self-Compacting Concrete Using Wood Waste Ash and Steel Slag

Abstract

Steel rolling mills are the main place where steel slag is produced. The steel slag accumulates at the bottom of the blast furnace slag. The current study sought to ascertain whether steel slag may replace some of the fine aggregate (sand) in self-compacting concrete. 15% of wood waste ash used as mineral admixture and varying amounts (15%, 30%, and 45%) of steel slag were used as sand replacement. Experimental tests were performed on freshly cured concrete that contained steel slag to determine its properties. Slump flow, U-box, L-box, V-funnel, splitting tensile strength, flexural strength, and elastic modulus are features of self-compacting concrete that comprises steel slag in a portion of river sand. Flexural Strength, and modulus of elasticity of Self-Compacting concrete incorporating steel slag in partial replacement of river sand were examined. The results of this study show that at a fixed water cement ratio of 0.45 and an SP dosage of 1.1% by weight of powder. Self-compacting concrete's compressive strength, splitting tensile strength, and flexural strength enhanced throughout the curing process.
