The activity of clinker is determined by the firing mode, chemical composition and properties of the feedstock. Among the factors affecting the quality of clinker, the dispersion of the raw material mixture plays a key role. It was revealed that the deterioration of cement clinker parameters is associated with insufficient fineness of grinding the components. Limestone grinding is of particular importance — it is its coarse grinding that has a more significant effect on clinker activity compared to a similar process for non-quartz material. Homogeneous fine grinding of all components leads to the formation of a fine-grained microstructure of clinker, which ensures the formation of dense cement stone with increased strength during hydration.

Keywords: limestone, clay, grinding fineness, clinker activity, cement stone.
