USE OF FERROCHROME SLAG AS AGGREGATE IN CONCRETE-

Ferrochrome slag (FS) is a solid waste residue that is obtained by the smelting process during the production of stainless steel in Ferroalloy industries. Review stone is focussed on the use of ferrochrome slag as an aggregate in concrete. The effect of FS on the properties of concrete such as workability, compressive strength etc are studied.

OverviewProductionUsage

Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Cr Ore (an oxide of chromium and iron) is reduced by coal and coke to form the iron-chromium alloy. The heat for this reaction can come from several forms, but typically from the electric arcformed between the tips of the electrodes in the bottom of the furnace and the furnace hearth. This arc creates temperatures of about 2,800 °C (5,070 °F). In the process of smelting, huge amounts of electric
