SU1209672A1 - Polymerconcrete mix - Google Patents

Description

The invention relates to the field of building materials, namely to the composition of polymer concrete mixes for floors of industrial buildings.

The purpose of the invention is to reduce the bulk resistivity and flammability of concrete.

For the tests, a polymer-concrete mixture is prepared according to known and proposed methods.

The proposed polymer concrete mix is prepared by mixing all the components in the following order s , 22: 0.55-0.75) 24.33

a C-220-5 brand mixer each subsequent component after 5 minutes of mixing the previous one. The viability of the mixture after mixing is 2-2.5 hours.

Colloidal graphite is a powder with a specific surface area of 1200 g / s m.

Andesitic flour, ground quartz sand, and other alkali-resistant and versatile fillers are often used as a filler.
