Current Context : Central Road Research Institute (CRRI) issued guidelines for Utilization and Processing of Steel Slag in Road Construction.
ABOUT STEEL SLAG
- It is a by-product of smelting ores and recycled metals.
- It is mainly a mixture of metal oxides and silicon dioxide.
- It is a solid waste generated during the conversion of iron into steel in a basic oxygen furnace (BOF) or during the melting of scrap to make steel.
- Key Applications: Road base course material (Steel Slag Road Technology (SSRT)), Blending material for Portland cement, Fertilizer and soil improvement etc.
Benefits of Steel Slag Road Technology : Improved durability of road, Improved skid resistance, Reduction of carbon footprint in road construction.
