FIELD: chemistry.
SUBSTANCE: invention relates to accelerating agent compositions containing inorganic compounds selected from calcium silicate hydrate (CSH), ettringite or AFm phases of calcium-containing inorganic compounds and a copolymer containing polyether macromonomers of thiovinyl ether and anionic monomers, wherein weight ratio of copolymer to calcium ranges from 1/20 to 20/1. In addition, it relates to methods of producing compositions and mixtures of construction materials containing compositions, and use of said compositions. Invention is developed in dependent claims.
EFFECT: technical result is acceleration of strength gain at early stages of hardening.
