POLYMER-CONCRETE MIX Russian patent published in 1994 - IPC

FIELD: preparation of polymer-concrete mixes. SUBSTANCE: the polymer-concrete mix comprises ( wt % ): 14-19 epoxy diane resin; 1.4-3.3 curing agent such as polyaminoimidazoline resin; 1.0-6.0 a mixture of petroleum polymer resin and styrene rectification still residue in a 1: 1 ratio; 0.8-2.2 zinc dimethyldithiocarbanate; and a mineral filler, the balance. The resistance coefficient after 28-day treatment with 10% H₂SO₄ and then 10-day treatment with 10% NaOH at 65 C is not greater than 0.52. The resistance coefficient after 28-day treatment with 10% HCl and after 10-day treatment with 20% NaOH of 65 % C is not greater than 0.46. The abrasive wear after treatment with sand when treated with 10% NaOH is not greater than 11.2% , when treated with 20% NaOH, is not greater than 13.8% , when treated with 10% HCL, is greater than 15.9% , and when treated with 20% HCl, is not greater than 17.3% . The strength losses after attrition in a clay-sand pulp are not greater than 2.3% . EFFECT: improved properties of the mix. 2 tbl
