•Examined the possibilities of using I-sand, a waste product generated from iron and steel industries, as a replacement for river sand as fine aggregates in RCC constructions.•Detailed mechanical, chemical and physical properties of I-sand in comparison with that of river sand for various mix proportions were systematically investigated.•Effective utilization of iron slag in reinforced concrete is possible without compromising on the quality and this could be an interesting method for the industrial waste disposal with the added advantage of conservation of natural resources and as an economically viable alternative.
