FIELD: chemistry.SUBSTANCE: inventions relate to protection of substrates against corrosion. Claimed is dispersible redispersible or water-soluble mixture for reinforcing construction materials and protection against corrosion, based on, at least, one water-soluble organic polymer and, at least, one organic silicon compound, which contains, at least, one SiOSi-bond, with content of organic polymer constituting approximately from 40 to 80 wt % counted per the sum of organic polymer and organic silicon compound; and organic silicon compound, which contains, at least, one SiOSi-bond, is based on oligomeric mixture of alkylalkoxysiloxanes, which contains from 50 to 100 wt % of alkylalkoxysiloxanes and has oligomerisation degree mainly from 2 to 20, with oligomer mixture of alkylalkoxysiloxanes satisfying the overall formula I: (R")Si(OR"')O(I), where groups R" represent similar or different linear, branched or cyclic alkyl radicals with 1-18 carbon atoms, mainly methyl, ethyl, propyl, hexyl, octyl, hexadecyl; groups R"' are similar or different and represent hydrogen or linear or branched alkyl radical with 1-4 carbon atoms, mainly methyl, ethyl, propyl, and 1,0<x<2,0 and 0,5<y?1,0, on condition that (2y+x)=3.EFFECT: creation of substance for protection of materials against corrosion, which can be added to dry construction mixtures both in form of powder and in form of liquid preparation, storage stability, ecological friendliness, and absence of interaction or very insignificant interaction with hydraulically binding components.18 cl, 4 tbl, 7 ex, 3 dwg |
