FIELD: chemistry.
SUBSTANCE: invention relates to composition of a polyfunctional superplasticiser for concrete mixture and mortar. The polyfunctional superplasticiser for concrete mixture and mortar, containing a water-reducing organic component, a mixture of sodium thiosulphate and sodium thiocyanate and water, contains the water-reducing organic component in form of superplasticiser SUPRANAFT and an additional mixture of resorcin, pyrocatechol and hydroquinone in ratio of (0.3-0.5):(6.45-8.01):(0.04-0.07), with the following ratio of components of the superplasticiser in wt %: superplasticiser SUPRANAFT 45.5-70.0, mixture of sodium thiosulphate and thiocyanate 13.48-15.4, said mixture of resorcin, pyrocatechol and hydroquinone 6.79-8.67, water - the rest. The invention is developed in subclaims.
EFFECT: wider range for regulating plasticising and air-entraining action of the polyfunctional plasticiser, as well as high strength in the early stages of hardening at higher doses of said plasticiser, high frost resistance.
