Geopolymer concrete is produced by replacing cement by alkali activated pozzolanic materials which are rich in silica and alumina. This experimental work involves an attempt to replace the natural coarse aggregate by steel slag. Steel slag obtained from steel rerolling mill is used as coarse aggregate to produce concrete and the performance of the concrete in terms of mechanical strength and durability are studied. This work presents the short – term performance of the geopolymer concrete in various aspects. Standard concrete grade M 40 is taken for the purpose of this study. With increase in demand over decades for a sustainable concrete which would minimize the use of natural sources to a possible limit, this work presents a concrete that would replace both cement and natural gravel in concrete by 100% with fly ash and steel slag, both being the industrial by-products seeking potential way of safe disposal to avoid environmental hazards. Also the availability of this industrial by-product is abundance in India, these can be used to produce eco-friendly concrete. The test results show that geopolymer concrete with scrap steel slag as coarse aggregate excels in performance in terms of mechanical and durability studies. Thus this can be suggested for structural applications widely.
