Jan 10, 2014· LD slag has a series of advantages over natural rock in the field of road construction. Greater hardness. Slag has a greater PSV (Polished Stone Value): i.e., greater resistance to wear. This is the result of its mineral composition. The consequences: less wear and longer road lifetimes. Roads constructed using LD slag demonstrate reduced rutting.

Management of steel slag (a major by-product of the steel industry) includes the treatment of highly alkaline leachate (pH > 11.5) from rainwater infiltration of slag deposits to prevent adverse impact upon surface or ground waters. This study aims to compare different treatment options for steel slag leachate through a life cycle assessment (LCA).

Life Cycle Assessment of Internal Recycling Options of ...

As recycled materials replace the raw materials that would otherwise have been required, the effects cover the whole supply chain. Taking the entire product life cycle into account, achieving a 20% increase in recycled material from 60% to a level of 80% prevents 1.2 tonnes of CO 2 emissions per tonne of stainless steel.
