Properties of concrete with partial replacement of steel slag with fine aggregate

摘要

Sustainability of natural resources is one of the great needs for India. Concrete, a major construction material requires a large quantity of natural resources in the fine aggregate, coarse aggregate, etc. To avoid environmental degradation the consumption of natural resources should be reduced by using alternate source. Due to industrialization enormous quantity of waste is produced as by-products, which can be effectively used as an alternate for the natural resources. Steel slag, one of the by-products obtained from manufacturing of iron and steel which can be used as partial replacement for fine aggregate in concrete thus by reducing the quantity of river sand. Compression test, split tensile test, flexural strength tests were carried out with 0 to 50% proportions of steel slag as replacement of fine aggregate. It was found that steel slag can be effectively used as a replacement for river sand.
