Description

The invention relates to building materials, in particular to compositions of polymer concrete mixtures based on furfurol acetone monomer, and can be used for the manufacture of chemically resistant structures and products.

The purpose of the invention is to improve the toughness and durability of polymeric concrete in chlorine.

The mixture is prepared as follows.

Into the concrete mixer loads furfurol acetone monomer, then, with {Mixing, inject the dry mixture. forsterite sludge with copper fluoride and ethylene imine eros. The resulting mixture is combined with a melt (benzenesulfonic acid) and crushed stone and sand from nickel slag are added. The mixture is stirred for 3-4 minutes and unloaded into molds. After 3-4 hours of curing at C, the products are disintegrated and heat treated in drying chambers at 80 ° C for 8 hours.
