POLYMER CONCRETE MIX Russian patent published in 1998 - IPC

FIELD: structures subjected to significant service effects and temperature fluctuations, more particularly repair of aerodrome and road coatings. SUBSTANCE: polymer concrete mix comprises epoxy resin, quartz sand, granite solidifier, oxidizer butadiene- piperylene copolymer having dynamic viscosity of 70-20 P at 25 C by Geppler viscosimeter with divinyl to piperylene unit weight ratio of (50-53.3):(40-42) and caking cement. Solidifier includes di(poly)isocyanate, the ratio of components being as follows (wt %): 9 oxidized butadiene-piperylene copolymer having dynamic viscosity of 70-140 P at 25 C by Geppler rheoviscosimeter with divinyl-piperylene unit weight ratio within (50- 53.3):(40-42); 1 di(poly)isocyanate; 1 epoxy resin; 27 quartz sand; 5 caking cement; and 53 crushed granite stone. EFFECT: improved properties of the polymer concrete mix. 2 tbl
