Replacement of Natural Coarse Aggregate by Industrial Steel Slag In Road Construction
Sudarshan B. Bhutekar,  Dr. B.M. Patil
Due to growing environmental awareness, as well as stricter regulations on managing industrial waste, the world is increasingly turning to researching properties of industrial waste and finding solutions on using its valuable component parts so that those might be used as secondary raw material in other industrial branches. Although steel slag is still today considered waste and is categorized in industrial waste catalogues in most countries in the world, it is most definitely not waste, neither by its physical and chemical properties not according to data on its use as valuable material for different purposes. Moreover, since the earliest times of the discovery and development of processes of steel and other metals production, slag as by-product is used for satisfying diverse human needs, from the production of medicines and agro-technical agents to production of cement and construction elements. This study demonstrates the possibilities of use of industrial steel slag as natural coarse aggregate in the road construction. Considering the specialty of physical and chemical properties of industrial slag and a series of possibilities for its use in road construction as a replacement of natural coarse aggregates.
