Steel Slag

News: Union Steel Minister inaugurated a six-lane highway in Surat made of steel slag -- a first in India.

About:
• The road constructed using 100 per cent steel-processed slag is a real example of converting ‘waste into wealth’ and improving sustainability of steel plants.
• The road has been jointly made by Central Road Research Institute (CRRI) - a laboratory of Council of Scientific and Industrial Research (CSIR) and ArcelorMittal Nippon Steel (AMNS) India.
• Slag is a by-product which comes out during manufacturing of steel through three processes, namely basic oxygen furnace (BOF) route, electric arc furnace (EAF) and induction furnace (IF).
• This is a breakthrough for the industry as far as utilisation of slag is concerned. Slag was being used only for only landfilling.
• Use of such material in road construction shall not only increase its durability but also help in reducing the cost of construction as slag-based materials have better properties than natural aggregates. The use of steel slag in road construction will also address the shortage of natural aggregates in the country.
