PROSPECTS OF CARBONATE ROCKS APPLICATION IN NEW GENERATION CONCRETE
The analysis of the use of finely dispersed microfillers in cement systems has been carried out. Possible mechanisms of the influence of calcite on the formation of the microstructure of cement materials are analyzed. Investigations of the influence of calcite on the formation of the initial structure and phase composition of the products of hydration of cement stone have been carried out. It is found that finely dispersed calcite densifies the structure and promotes the activation of the formation of hydrate phases and solid solutions, which increase the strength of cement materials. Investigations of the effect of carbonate micro-filler on the strength of cement-sand mortars and concretes have been carried out.
