The article is devoted to the study of the cement stone hydrate phases formation in the presence of significant amounts (2%) of isomeric disaccharides - sucrose, maltose and lactose. Attention to disaccharides as modifying agents of cement stone is due to their ability to influence the ratio of high and low density cement gels in the composition of cement stone. To implement Portland cement hydration process in the presence of significant amounts of disaccharides cement grinding in the presence of carbohydrate solutions was used. It was found that the molecular structure of carbohydrate does not affect the elemental and phase composition of hydration products. Hydrosilicates in the presence of carbohydrates and aside of the molecular structure of the latter form the phases of the cryptocrystalline structure. The formation of cryptocrystalline phases is accompanied by occlusion of disaccharides; the residual content of disaccharides in the liquid phase of suspensions does not exceed 0.3% of the initial amount of modifying carbohydrate.
