Abstract: Aggregate is one of the main ingredients in producing concrete. It is 75% of the concrete. The strength of the concrete produced is dependent on the properties of aggregates used. There is huge demand for this material. Hence need for an alternative coarse aggregate arises. The scope of project was to investigate the possibility of using sponge iron scrap material as an alternative material to coarse aggregate in structural concrete. Experimental investigation was carried out on compressive strength and durability related tests such as acid resistance test and Permeability. Tests were conducted by replacing the coarse aggregates in concrete mixes by sponge iron scrap material. From the experimental investigation it was found that sponge iron scrap material can be used as an alternative for coarse aggregate in concrete. However further investigations have to be made to study long term effects.
