- Аннотация: The aim of our investigation was the study of hydration and structure formation of cement contained sulphoferrite phases. The different methods were used: XRD, EPMA and chemical selective dissolution methods. It was shown at hydration of sulphoferrite phases Fe-rich ettringite was crystallizated. Its habit of crystal is dendrite which desintegrate on the separate crystals. Many of them contain Si. It can be explained dy their penetration into gel C-S-H. The other crystals of Ferich ettringite do not contain Si. It was promoted by their late formation at hardening. Crystallization of Fe-rich ettringite did not accompanied by destruction but it packed cement paste.
