FIELD: chemistry.
SUBSTANCE: binder, which contains portland cement, a ground silica-containing component and an alkaline activator with metal cations, contains as the ground silica-containing component quartz sand with specific surface area of 300 m2/kg, as said activator Humate +7 with pH 12-13, added in form of a 2% aqueous solution by mixing with said sand and holding for 10 minutes, with the following ratio of components, wt %: portland cement 70-85, said sand 15-30, said Humate +7 0.1-0.2 per dry substance over 100.
EFFECT: high compression strength after 28 days, wider range of use of an alkaline activator for a silicon-containing component, simple production technique.
