✦ Synopsis

Hydration and hydraulic properties of the quaternary phase Q = C20A13M~S 3 were investigated. The phase is located in the subsystem C2S-CA-C~AT-M~) ih th~ z-one of the variable mineral composition of high alumina cern~nts (HACk. Relations between the composition of the Q phase and the phase composition of its hydration products were determined. Influence of the hydration processes and the formation of hydrates on the physico-mechanical properties of the system during setting and hardening at room temperature or at hydrothermal conditions (190"C, saturated vapour pressure) was established. It was proved that the hydraulic properties of the Q phase are close to those of the high alumina cements.
