FIELD: chemistry.SUBSTANCE: invention relates to building materials and can be used in applying fire-retardant coatings on building structures. The fire-retardant composition in form of a water-tempered dry mixture for applying coatings is characterised by that it contains, wt %: portland cement 20.0-60.0, expanded vermiculite 10.0-40.0, chrysotile asbestos 5.0-25.0, chamotte 5.0-25.0, expanded pearlite 10.0-30.0, polyfunctional concrete modifier 0.1-1.0, fine water-soluble adhesive 2.0-8.0 and a water-retaining additive 0.1-3.0.EFFECT: improved crack resistance owing to strain redistribution on the whole material.2 tbl |
