FIELD: construction.
SUBSTANCE: method of dry construction mixture production for foamed concrete manufacture provides for mixing dry mineral binder, dry fine mineral filler, metal sulphate and protein-containing additive. Fine mineral filler is used with fractions sizing from 0 to 0.315 mm and protein-containing additive is used as 30% colloidal solution of protein-containing concentrate in water at the following ratio of components, wt %: mineral binder 41-58, the said fine filler 26-48, the said protein-containing additive 9-15, metal sulphate 1-2. Dry construction mixture for foamed concrete manufacture is produced by the method as disclosed by this invention.
EFFECT: simplified technology, increased strength characteristics, extended shelf life.
