FIELD: construction.
SUBSTANCE: invention relates to a construction chemical composition for construction materials containing inorganic binding substances. Construction chemical composition contains a bisulphite adduct of glyoxylic acid or its salt or a mixed salt and an inorganic binder. Construction chemical composition is used to modify hardening of building materials compositions containing inorganic binder, and/or to obtain construction articles, particularly for concrete.
EFFECT: technical result is provision of time to initial setting sufficient for maintaining good processability, for example, measured by rheological behavior of mortar during this time, fast setting and high strength.
