Global crude steel production in 2018 was approximately 1807.1 Mta. 70.8 % of the current crude steel production is accounted for by the BOF process, 28.8 % by the EAF process (Fig. 3) and only 0.4 % by other processes such as the Siemens Martin process. Derived from these figures, the annual quantities of steelworks slag amount to a total of 250 Mta, of which around 65 % are BOF or LD slags

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, 2CaO·SiO2, 2CaO·Fe2O3. We have proved and first pointed out that the steel slag induces phase transition during grinding process and the Blaine
