Overview:
Recently, the member (Science) of Niti Aayog released the Guidelines for Utilization and Processing of Steel Slag as Processed Steel Slag Aggregates in Road Construction.
About Steel Slag:
- Steel slag is an industrial byproduct obtained from the steel manufacturing industry.
- It is produced in large quantities during steel-making operations that use electric arc furnaces.
- It can also be produced by smelting iron ore in a basic oxygen furnace.
- Primarily, slag consists of calcium, magnesium, manganese and aluminium silicates and oxides in various combinations.
- The cooling process of slag is responsible mainly for generating different types of slags required for various end-use consumers
Applications of Steel Slag
- It has found use as a barrier material remedy for waste sites where heavy metals tend to leach into the surrounding environment.
- Steel slag forces the heavy metals to drop out of solution in water run off because of its high oxide mineral content.
- It has been used successfully to treat acidic water discharges from abandoned mines.
- It can replace coarse aggregate due to a higher impact and crushing strength, better anti-skid capacity.
Q1: What is a blast furnace?
It is a large structure in which iron ore is heated under pressure so that it melts and pure iron metal separates out and can be collected
