We study the influence of admixtures on the linear expansion of cement stone. By the method of mathematical planning of the experiments, we determined the optimal relationship between the expanding components in the composition of cement. The importance of simultaneous introduction of several components is explained not only by the expanding action of each of these components but also by their mutual influence. Gypsum is used not only as an inhibitor of the hydration of lime but also as a sulfate component used for the formation of calcium hexasulfoaluminate in the later stages of solidification. This enables us to affect both the formation of crystal structure and the strength of the cement stone in general. We also performed mathematical processing of the results of experimental investigations.
