METHOD FOR MODIFYING STEEL MAKING SLAG AND MODIFIED STEEL MAKING SLAG

摘要

PROBLEM TO BE SOLVED: To provide a method for modifying steel making slag to improve the method for reducing not only the free CaO but also the water absorption and the modified steel making slag.;SOLUTION: The steel making slag is modified by mixing substances containing SiO₂ and Al₂O₃ (e.g. blast furnace slag, desiliconized slag, fly ash, waste glass, concrete waste, waste brick, aluminum ash, aluminum dross, aluminum smelting slag, incinerator ash of urban waste/sewage sludge, ash melting slag, sewage sludge melting slag, car shredder dust incineration ash, etc.) with the steel making slag and heat-treating at a temperature ≥1,100°C.;COPYRIGHT: (C)2004,JPO
