Electric arc furnace slag: study on leaching mechanisms and stabilization treatments

摘要

Studies conducted over the past 15 years have demonstrated the technical suitability of the Electric Arc Furnace slag (EAF) as an alternative to natural stone materials. Steel slag can be profitable used for civil applications such as road surfaces layer, foundations and embankments or concrete aggregates. However, a strong limitation to their use is due to the presence of toxic metals (Ba, Cr, V, Mo,...) that can be released into the environment in particular conditions, especiall), for unbound products in which the slag can come into contact with water.
