Abstract

Modification of the structure of gypsum-cement-pozzolan binder allows you to expand the range of gypsum binders for creating dry building mixes and structural elements of low-rise buildings. It was found that in the presence of functional additives, the character of crystallization of hydrate neoplasms changes, which leads to a change in the properties of the hardened binder. The study of the effect of individual and complex additives on the properties of gypsum-cement-pozzolan binder allowed us to develop water-resistant gypsum binders.
