Evaluation of the steel slag incorporation as coarse ...

Sep 01, 2016 · In particular, steel slag represents a significant proportion of these by-products (Proctor et al., 2000); for instance, the production of 3 tonnes of stainless steel is estimated to generate about 1 tonne of stainless steel slag. Consequently, a large amount of steel slag is yearly produced in the world (around fifty million tonnes per year).

The use and advantages of slag - voestalpine

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.
