FIELD: construction. ^ SUBSTANCE: composition contains the following components, wt. calcium polysulfide 15-20, monoatomic alcohols of normal or isomeric structure 0.02-0.05, water - balance. The monoatomic alcohols are ethyl, propyl or isopropyl alcohol, at the same time the composition for treatment has density of 1.15-1.20 g/cm3. Method of construction materials treatment includes impregnation with the above-specified composition for 1-5 hours in amount of 2.0-2.5 kg/m2. Treatment is carried out at room temperature and atmospheric pressure. ^ EFFECT: higher strength, frost resistance and chemical resistance of construction materials, their lower water consumption with simultaneous simplification of method of construction materials treatment and reduction of energy intensity. ^ 7 cl, 1 tbl |
