Development of Concrete by Partial Replacement of Fine Aggregate by GBFS

Sustainable construction mainly aims at reduction of negative environmental impact resulted by construction industry which is the largest consumer of natural resources. Over period of time, waste management as become one of the most complex and challenging problem in the world which affects the environment. The rapid growth of industrialization gave birth to numerous kinds of waste by-products which are environmentally hazard and creates problem of storage. The consumption Granular Blast Furnace Slag (GBFS) in Concrete not only helps in reducing greenhouse gases but also helps in making environmentally friendly material. This paper shows the effects of replacing fine aggregate with that of Granular Blast Furnace Slag in concrete properties. The basic objective of this paper was to identify alternative source of good quality fine aggregates which is depleting way very fast due to the fast pace of construction activities. In India the uses of GBFS as waste industrial by-product of iron and steel production provides great opportunity to utilize. It as an alternative to normally available fine aggregate M20. Concrete of M20 grade is considered for a WC ratio of 0.40 for the replacement of 0%, 25%, 75% and 100% of GBFS. The investigation revealed improvement in workability, compressive strength and split tensile strength.
