Beschreibung
Zusammenfassung:	FIELD: manufacture of building materials. ^ SUBSTANCE: invention relates to compositions of building mortars with elevated viability and frost resistance for laying constructions with bricks, concrete stones, and light-rock stones. Building mortar composed of Portland cement (14.0-18.0%), sand (64.0-69.0%), and water further contains 0.003-0.2% sodium chloride and 0.8-2.5% fatty acid derivatives, in particular, alkali effluent from vegetable oil production containing 0.1 to 0.7% free alkali. ^ EFFECT: increased strength and frost resistance of mortar with reduced stratification. ^ 3 tbl, 20 ex
