HYDRO-ISOLATING DECORATIVE PLASTER FOR CONCRETE RESERVOIRS

Abstract

Development of Ukrainian build materials production takes place in the direction of new competitive dry build mixtures creation with polyfunctional and decorative setting, including for implementation of hard hydro-isolating plaster of concrete reservoirs, assuming introduction of dyes-pigments either directly in the complement of mixture or in the special composition for implementation of decorative integumentary layer. The competitiveness of such dry build mixture is provided by the innovative decision on plasticiting, compacting and hydro-phobization at hydrative hardening of Portland-cement composition due to introduction to its composition in small concentrations of inexpensive and unscarce additions, in particular, of calcium nitrate. For expansion of application domain of such hydro-isolating compositions introduction of pigments-dyes with the simultaneous presence of modifying additions is possible, in particular, of ammonium sulfate, sulfite yeast brew or technical lignosulfonate (in the amount of to 0,2 mass. %) or redispersible powders of a vinyl-acetate type (to 0,005 – 0,1 mass. % from mass of cement). Scenery of the hard hydro-isolating plaster executed on the basis of base dry build mixture assumes application of the prepared compositions present at the market of build materials of Ukraine (for example, Ceresit CT-64).
