The cooling process may be assisted by the controlled application of water. Air-cooled blastfurnace slag hardens by hydraulic reaction and carbonation. 3.4 air-cooled steel slag aggregate made mainly of crystalline calcium silicates and calcium ferrites comprising CaO, SiO2, MgO and iron oxides, obtained by slow air cooling of molten steel slag NOTE The cooling process may be assisted by the controlled application of water. Air-cooled steel slag hardens mainly by carbonatic reactions. 3.5 granulated blast furnace slag glassy, sandy material made up mainly of CaO, SiO2, Al2O3 and MgO, produced generally by rapid water quenching of molten blast furnace slag NOTE 1 Granulated blast furnace slag hardens by hydraulic reaction. NOTE 2 Pelletized and dry granulated blastfurnace slag may have similar hydraulic properties. SIST EN 14227-2:2004
