Abstract

The study is devoted to the development of a self-leveling dry building mixture, based on a mixed gypsum-cement-pozzolanic binder. It is noted that the compositions on gypsum-cement-pozzolanic binder combine the positive properties of both cement and gypsum binders. In order to give the mortar mixture the required set of properties, the plasticizers, rheology modifiers, hardening retardants, reinforcing fibers, quartz and dolomite sands were introduced into the composition. The developed composition meets all the requirements of regulatory documents and can be recommended for use in industry.

Key words:

dry building mixtures, self-leveling mixtures, gypsum-cement-pozzolanic binder, concrete admixtures
