Mechanochemical Processing of Ultrafine Steel Slag

Mechanical grinding of steel slag is investigated and characterized using X-ray diffraction and size analyzer. The results indicate that the obtained ultrafine powders contain active mineral phases suitable for ordinary Portland cement (OPC)-Ca(OH)2, 2CaOSiO2, 2CaOFe2O3. We have proved and first pointed out that the steel slag induces phase transition during grinding process and the Blaine ...
