【 摘 要 】

Usually, sulfoaluminate clinker or a mixture of aluminate clinker with calcium sulphates is used to obtain expansive cements. For these cements ettringite is an important hydration product. This paper deals with the composition and properties of solid solution of calcium aluminate. It was studied an influence of calcium aluminate on structure and properties cement phases. The properties of cements containing these phase were also studied. The investigation of hydration and properties of aluminate cements shows that ettringite and its analogies are formed thus providing expansion and compression of cement stone.
