FIELD: construction.
SUBSTANCE: present invention relates to a composition for a construction mixture comprising (α) at least one inorganic binder and (β) at least one water-soluble copolymer based on (a) 0.1–20 wt. % of at least one monomer of formula (I) and (b) 25–99.9 wt. % of at least one hydrophilic monomer (b), which differs from monomer (a), where at least one copolymer has an average molar weight of M 1,500,000-30,000,000 g/mol. Also disclosed is a method of producing said composition. Additional object of this invention is use of copolymer component (β) as a rheological additive in the composition of the invention. Invention is developed in dependent claims.
EFFECT: technical result is prevention of layering of composition of inorganic binding substances and high its fluidity.
