BLAST-FURNACE SLAG, AGGREGATE FOR ROADS AND CONCRETE

LE LAITIER DE HAUT FOURNEAU, GRANULAT POUR ROUTES ET POUR BETONS

This article reviews the origin, chemical and mineralogical nature of blast-furnace slag. The three methods of manufacturing crystallized slag are described: (1) poured in pockets and cooled in pits; (2) directly poured and cooled in pits; (3) expanded slag and granulated slag. Physical and physico-chemical characteristics are mentioned: density, porosity and porosity/bulk density, porosity/mechanical strength relations, water absorption and capillary rise, shape, thermal and sound insulation, durability, frost-thaw behaviour; mechanical characteristics are also described: compressive strength, resistance to shock and wear. Blast-furnace slag can be used: (1) in road construction (list of French standards and specifications, test procedures, directives), (list of standards from Germany, Belgium, Great Britain, Luxembourg, Poland); (2) in civil engineering with list of French and other standards.
