And depending on
The kinetics of hydration is limited by the rate of dissolution of minerals in the liquid phase, the values of the shipment of hydration products achieved in it, primarily the hydrate of calcium oxide. The rate of dissolution, in turn, depends on the specific surface of the dissolving substances and the degree of their forwarding in the solution. Due to the fact that the particles of cement can be monomineral and polymineral, the degree of shipping of hydration products in the liquid phase on contacts with a solid phase will be different. The composition of the liquid phase and depending on the radii of microcapillaries, it is determined by the rate of diffusion of ions from the surface of the solid phase. The presence of monomineral particles in the cement is confirmed by the size of the crystals of Alita and Belita in cement. The average size of the cement particles is in the range of 20-35 MK.
