Abstract The effects of adding magnesium slag into raw meal on clinker calcination, roller mill system operation and the cement performance using it as admixture were studied through experiments. When the content of magnesium slag in raw meal is ≥8.0%, it can significantly improve the burnability of raw meal and significantly increase the compressive strength of clinker. The magnesium slag contains CaF2, which can act as mineralizer and crystal seed and improve the burnability of raw meal. Using magnesium slag instead of limestone, slag and other non-active admixture in cement can improve the compressive strength of cement for 3 days without affecting the anti-shrinkage performance of cement.
