Sulfoaluminate Cements Composition and Properties

Abstract

The chemical and mineral composition, physico-mechanical properties of sulfoaluminate cements of various classes of strength manufactured in China which are used in Russia to build and repair buildings and structures have been considered. It is shown that the sample sulfoaluminate cement depending on the strength class differ not only in chemical and mineral compositions, but also in their hydrophysical properties, kinetics of dissipation and hardening of cement, and hydration products. It is established that with the increasing strength class of the cement content it has calcium increases, the adhesion of the cement paste is slowed down, the duration of heat dissipation increases, the temperature dissipation is reduced, the hardening of the cement stone slows down.
