Abstract. Because of the unique physical and chemical characteristics of steel slag, steel slag aggregate (SSA) has been recycled into Portland cement concrete as a substitution for natural aggregates as a sustainable and low impact design solution by reducing the use of natural resources and the landfills for disposal.
In concrete steel slag has been incorporated as cementing material/aggregate, which increases the strength of concrete with the utmost result obtained is 67% of steel slag replacement for recycled aggregate (Qasrawi, 2014 ).
Abstract—Most of the volume of concrete is aggregates. Replacing all or some portion of natural aggregates with steel slag would lead to considerable environmental benefits. The primary aim of this research was to evaluate the durability of concrete made with steel slag as replacement for aggregates. For this present study M20 concrete will be designed. …
This study aims to investigate the effect of waste steel slag (SS) as partially replaced with cement and fine aggregate on concrete for different mixes in terms of compressive strength (CS) and electrical resistivity (ER). SS is a molten mixture of silicates and oxides that solidifies upon cooling, a byproduct of the steel-making process. Before …
This paper analyses the environmental impact of replacing high-quality coarse aggregates by electric arc furnace (EAF) steel slag. A Life Cycle Assessment (LCA) was performed on three asphalt mixtures containing different aggregates: namely ophite, slag 1 and slag 2.
The purposed work aims at exploring the feasibility of utilizing the steel slag and RHA as a substitute to natural aggregates as well as cement in the cement concrete. Because of the existence of un hydrated free-lime and magnesium-oxide, which hydrate in a moist environment, the Steel Slag Aggregates (SSA) can expand. David Bonen [2].
Steel slag has higher strength characteristics than normal aggregate, which result in more strength differences between slag aggregate concrete and natural aggregate concrete. If the replacement of steel slag increases beyond 75%, to maintain the workability of concrete certain water reducing admixtures should be added.
