Replacing of Energy Optimizing Furnace Slag as a Fine Aggregate in Concrete

Concrete is largest produced material in the construction industry and as per WHO concrete is the largest consumed material by human beings after food and water. About 75% of the concrete is composed of aggregates and because of huge demand of concrete all over the world, availability of natural aggregates is ecoming scarce. Civil engineers have always been looking for an alternative for the use of more ecofriendly and easily available materials as a replacement to conventional constituents in concrete. Concrete industry has always welcomed the use of various industrial waste materials as a replacement to these constituents since, otherwise such industrial waste need to be disposed in the form of landfills causing enormous amount of land pollution. This project presents the experimental investigation carried out to evaluate the effect of partial replacement of fine aggregate in concrete by steel slag which is waste product generated during the production of steel. The use of steel slag reduces the need of natural rock as constructional material, hence preserving our natural rock resources besides provides an environmental friendly option of concrete production. Steel slag mainly consists of calcium carbonate and is produced as a byproduct of oxidation process in steel industry.
