Comparative Study of the Nature of Slag in the Formulation of Concrete Pavers

By Zakia Rais, N. H. Mtarfia, M. Taleb A., W. Maherzic

Abstract: The steel mill generates about 8000 tons/year of slag by transforming scrap metal to produce more than 60000 tons/year of wire rod and steel reinforcing bars. These co-products are stored or used for backfill. With this almost inexhaustible slag deposit, Morocco has a valuable resource thanks to its high content of silicates, lime and metal oxides. This has led to the attempt to valorize it in the manufacture of paving …
