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 composit
The CaO-rich portions of the systems CaO-A~203-SiO2-K2SO,, CaO-AC203-K2SO,-CaSO,, CaO-A~203-SiO2-K2SO,-CaSO, and CaO-A~203-Fe203-CaSO,-K2SO, have been studied experimentally. Schemes are presented showing phase assemblages compatible at subsolidus temperatures. Melting commences at about 825°C in as
To explain the initial hydration of quick cements of the system CllA7 • CaF2-C2S-Ct(A,F), their S03/Al203 ratio was varied, Portland cement was added to increase the alcalinity of the pore solution in the cement stone, and setting retarder was used during the tests. The process of hydration was inve
