FIELD: manufacture of building materials.
SUBSTANCE: invention proposes composition of chemical additive for cement concretes and is pretended for use in construction of reinforced-concrete installation. Additive, in particular, contains 5.0-10.0% sodium chloride, 20.0-40.-% potassium carbonate, and sodium sulfate - the rest.
EFFECT: increased strength in early solidification phases under heat-moisture treatment of reinforced-concrete parts and reduced consumption of additive.
