Utilization of Slag as an Aggregate Replacement for Road Base/Subbase Layers

Abstract

Ferrochrome and Steel slags are by-products of the stainless steel and steel production, respectively. The utilization of slag as an aggregate replacement to provide a sustainable solution has gained attention from the construction industry in recent years. By reducing the demand for natural aggregate and providing an alternative use for industrial waste products, the use of slag is an environmentally conscious and economically viable option. This paper focuses on the potential application of using slag as road base/subbase layers. The paper examines the physical and chemical properties of the slag and reports on the strength and toxic metal analysis results. Slag can be processed into a coarse and fine aggregate that satisfies the necessary standards for road base/subbase layers. The testing results highlight the successfulness of using slag as an aggregate replacement for base/subbase layers, making it a promising and sustainable solution for the construction industry.
