FIELD: building materials, in particular concrete additives (plasticizer).
SUBSTANCE: method includes centrifugal preseparation of distillery dreg to provide concentrate, treatment obtained concentrate with alkali carbonate to pH 8-11, followed by addition of superplasticizer or lignosulfonate solution providing ratio of total amount of alkali carbonate and concentrate to amount of solution ‹1. Superplasticizer or lignosulfonate solution is added to obtained centrifuge effluent, providing ratio of centrifuge effluent to said solution from 0.2 to 2.0 to produce another plasticizer. Dry alkali carbonate content is not more than biomass content in raw distillery dreg. Method of present invention is useful in concrete mixtures manufacturing for producing of precast concrete and cast-in-place constructions.
EFFECT: concrete mixtures with controlled flow characteristic and concrete curing rate.
