Are Steel Slags the Future of Sustainable Infrastructure?

Steel slag is a mixture of metal oxides and silicate, and is produced as a by-product during manufacture of iron and steel. However, iron and steel slag is non-metallic in nature and does not have hazardous materials.

The construction industry is leaning towards use of slag for its properties and being environmental-friendly. There are different types of slag generated from the steel making process. The most common slags are Electric Arc Furnace (EAF) slag, LF slag and Steel Furnace Slag (SFS). Some of the world’s largest economies, including the USA, Brazil, European Union, China and Australia are using EAF and LD Slag for many applications.
