The article shows and confirms the possibility of using natural wollastonite as a mineral additive capable of binding lime in cement stone in the pozzolanic reaction. As a result of this reaction, an additional amount of the C-S-H phase is formed, since the main phase (50-70%) of the hardening cement stone is the C-S-H phase, in the structure of which diorthosilicate or pentameric formations of silicon-oxygen anions are distinguished. The wollastonite-based additive exhibits a positive effect during concrete hardening. This effect is explained by the influence of the wollastonite surface on the formation of the phase composition of cement stone and concrete.
