Investigation of physico-chemical processes forming the structure of waterresistant composite materials based on modified gypsum binders

Abstract

The article presents the results of studies of the physico-chemical processes of forming the structure of
the material and the development of effective compositions of modified gypsum-carbonate composite
gypsum materials based on gypsum binder, microcalcite and modifying polymer additives, contributing
to the improvement of their rheological and physico-mechanical properties and, accordingly, to increase
the bending strength of building decorative ceiling suspended gypsum boards based on them. As a result,
it became possible to organize the production of ceiling-mounted suspended composite gypsum boards
with high water resistance and physico-mechanical properties and low cost, as well as the widespread
use of this board in the construction of residential buildings and construction structures in the republic
