FIELD: building materials.
SUBSTANCE: invention is related to production of dry building mixtures, and can be used for insulating and corrosion-protective coatings for external and internal finishing of buildings and structures for various purposes. The dry building mixture contains, wt.%: Portland cement 15.2-45.7, quartz sand with MS equal to 2.0-2.5 48.6-81.7, wollastonite with particle sizes from 2 to 60 microns 1.5-4.9, a complex additive including superplasticizer powder C-3 0.1-0.5 and calcium or zinc stearate 0.1-0.3.
EFFECT: production of a dry construction mixture of high density, increasing the strength, water resistance, resistance to the effects of low-mineralized waters and chlorine-containing solutions of the coating made using the building mixture.
