Mix Design of Roller Compacted Concrete Pavement Using Steel Slag By-Products
Significant quantities of steel by-product materials are generated yearly worldwide. In their raw states, slag materials are considered unsuitable for reuse without processing. Since traditional storage and disposal strategies are neither environmentally friendly nor sustainable, their reuse as alternate materials can be economically and ecologically beneficial in various engineering and construction applications. This paper evaluates use of slag materials in roller compacted concrete (RCC) pavements. Slag materials were subjected to physical and chemical laboratory testing to determine their engineering properties. Twelve mix designs were developed and included graded slag aggregates, cementitious materials, water, and air-entrained admixtures to provide an optimal mix. The resulting optimal mix included 13% cementitious (50% Portland cement, 30% slag cement, and 20% fly ash). This study demonstrated the feasibility and beneficial reuse of steel slag materials in RCC pavements with potential cost savings at a former steel plant site in Maryland with over 5-million tons of stockpiles.
