The results of studies of the influence of aleuropelite rocks of the Ishim Suite of the South of the Tyumen region on the synthesis of structure-forming hydrosilicates and the formation of properties of lime-silicate material obtained by autoclave hardening are presented.. The peculiarities of the compactibility of the silicate mass and it is found that the introduction of aleuropelites improves the molding properties and increases the plastic strength. It is revealed that in the process of hydrothermal synthesis of the mixture with the use of aleuropelites, the main structure-forming phases are xonotlite, abnormal tobermorite, tobermorite of triclinic crystal system. The article presents the results of electron microscopy, confirming a positive role (effect) of aleuropelites on the processes of synthesis. The impact of aleuropelitess on the degree of compaction of the raw mass and the processes of physical and chemical interactions during hydrothermal regime makes it possible to improve the strength and water resistance of silicate stone.
