Experimental Study on Iron Ore Tailings as Aggregate in Development of Bricks and Concrete
Keywords:Bricks, Concrete, Compressive Strength, Iron Ore Tailings, Perlite
The present study focuses using iron ore tailings in construction. The construction industry is in need of easily available, economically feasible and green materials. This chapter deals with the study of manufacturing bricks and concrete made from iron ore tailings and a few studies were carried out using additive like perlite. The physical and chemical properties of the materials used in the study were determined as per Indian standards and the strength properties were determined. Initially, it was found that, Iron Ore Tailings (IOT) made bricks were found to be denser but after adding perlite the density of bricks decreased considerably and the optimum strength was observed with the addition of perlite by 5% with IOT at 50%. In case of IOT concrete mixes, slump value of concrete reduced with increase in perlite content. The optimum strength of concrete was 51.00 MPa with IOT-alccofine-perlite at 30-10-2.5%. Hence, bricks and concrete can be produced by replacing IOT without compromising the strength and durability properties and also helps in greener environment by utilizing the waste produced at mine sites, which also avoids dump maintenance issues.
