Abstract

With the rapid industrial growth globally, steel industries, in particular, are producing huge quantity of slag as by-product in different forms obtained through various cooling processes. These by-products are environmentally hazardous, create problems of storage, thereby reducing effective land-use affecting economy of the country. That is why, proper utilization of such waste materials and its management has become one of the most complex and challenging tasks over a period of time. Present study basically aims at investigating the scope of use of such a by-product Granulated Blast Furnace Slag (GBFS) as fine aggregate replacing natural sand partially or fully in concrete structures, in order to reduce environmental problems and waste disposal, also in terms of preserving natural resources. In this experimental investigation, design mix of various grades are prepared with various percentages of replacement of natural sand by GBFS. Based on the test results and detail investigation of cubes, cylinders and prisms, it is observed that GBFScan be utilized partially up-to 70% as alternative construction material replacing natural sand in concrete structures. Of course, the reduction in workability in such cases has to be enhanced to the desired level by adding suitable percentage of super plasticizer for higher percentages of replacements.
