FIELD: chemistry.
SUBSTANCE: invention relates to the compositions of additives for concrete and mortars based on portland cement. The plasticiser for ready-mixed concrete mixtures contains disodium hydroxyethylidene diphosphonate and sodium lignosulfonate, with the following component ratio, wt %: disodium hydroxyethylidene diphosphonate 30-35, sodium lignosulfonate 65-70.
EFFECT: increased mobility, water reduction, water resistance and preservation time of the concrete mixture.
