POLYMERIC CONCRETE MIX Russian patent published in 1995 - IPC

FIELD: manufacture of building materials. SUBSTANCE: the polymeric concrete mix comprises, as an amine hardener, a mixture of polyoxypropylene amine with a molecular weight of 480-550 with dicyanoethyldiethylene triamine in a 1-3:1 ratio or a mixture of polyethylene amine with a molecular weight of 180-220 with dicyanoethyldiethylene triamine in a (- .33-1): ratio, the ratio of the components being as follows (wt %): 23.5-30.3 epoxydiane resin; 30.3-35.5 trig chloropolyol resin; 11.6-12.2 said amine hardener; 27.2-29.6 quartz sand. The resulting polymeric concrete has Grecelli attrition up to 0,003 g/cm², a water absorption of up 0.18 % for 24 hours and a deactivation coefficient of up to 0.2. EFFECT: improved properties of the building materials. 2 tbl
