G.Murali, et.al. [5]concluded that the concrete with Steel Powder as waste material was found to be good in compres-sion which had the compressive strength of 41.25% more than the conventional concrete. Better split tensile strength was achieved with the addition of the steel powder waste in concrete. The strength has increased upto 40.87% when com-Utilization of Steel Slag in Concrete as Coarse Aggregate,concrete as coarse aggregate was carried out for the sustainable use of construction materials in Bangladesh [Mohammed et al 2015]. Investigations on other possible alternatives, such as steel slag may be conducted. The demand of steel in Bangladesh is estimated at about 3 million metric ton with 2.5% growth in each year. During production of steel, a significant portion of by-product (5-6% of total weight of steelUtilization of Linz–Donawitz slag from steel industry for,,27/01/2020· Coal fly ash is one of the solid residues generated from coal-firing power stations and used in cement clinkers, concrete production, road embankment, waste stabilization/solidification, geopolymer concrete, etc. The incorporation of these resource materials is not only helping in waste management but also reduces handling cost of wastes. The production of steel slag around the world is increasing over the time. The integrated steel plants generate about 150–200 kg of waste,Use of selected industrial waste materials in concrete,,13/09/2011· For concrete containing chromite industry waste (C), it was found that the initial and the final setting times increased with the increase of chromite industry waste replacement. The highest retardation of the setting times occurred at 15% of chromite industry waste replacement, which resulted in 3 h 30 min for the initial setting time and 4 h 57 min for the final setting time. This is due to a high replacement of cement by chromite industry waste…UTILIZATION OF SOLID WASTES GENERATED FROM STEEL PLANT,production of refractory are also performed in varying magnitude inside the steel works. A large quantity of waste is generated as a sequel to such Activities. To make one-tonne of crude steel even with good raw materials and efficient operation, 5 tonnes of air, 2.8 tonnes of raw materials and 2.5 tonnes of water are required. These will produce in addition to 1 tonne ofAn Experimental Study on Utilization of Iron Ore Tailings,,and Waste Glass Powder in Concrete Bakulamba Devi T S 1, Natesh M G 2,, ore as a number of steel plants have been planned for future in many parts of the country. In order to reduce the adverse impact of indiscriminate mining of natural sand, iron ore tailings which is the waste products of mining industries is used as an alternative to the river sand in the manufacturing of concrete.

Utilization of tailings in cement and concrete: A review
One of the advantages of cement and the cement concrete industry in sustainability is the ability to utilize large amounts of industrial solid wastes such as fly ash and ground granulated blast furnace slag. Tailings are solid wastes of the ore beneficiation process in the extractive industry and are available in huge amounts in some countries.

Firstly, the raw materials of mixing were analyzed, and the test ratio was determined. Secondly, the workability and mechanical property of concrete specimens with different amounts of iron ore,Waste Disposal and Recycling in Steel Industry,The steel industry needs scrap to produce new steel, which ensures that all steel products contain anywhere from 25 percent up to 100 percent recycled content. It also is cheaper to recycle steel than it is to mine virgin ore to manufacture new steel.
