The article is devoted to the study of the influence of dispersion of raw mixtbres on the properties of Portland cement clinker. The study established that the mechanical activation of raw mixtures by hydrodynamic effects significantly accelerates the processes of mineral formation during the synthesis of clinkers. In this case the microstructure and phase composition of clinkers changes. Clinkers from activated mixtures are characterized by clear crystallization of minerals, their uniform distribution and increased content of the alite phase. This determines the high mechanical strength of cements based on these clinkers. At the use mechanical activation of waste it is possible to obtain high level activity one.
