Description

The invention relates to building materials, in particular, compositions of polymer concrete mixtures used for the manufacture of chemically resistant products for underfloor heating.

The purpose of the invention is the improvement of chemical resistance and a decrease in the rate of heat absorption.

The specific formulations of the proposed and known polymer concrete mixtures subjected to the tests are listed in Table 1.

In the proposed mixture, sulphite-yeast mash is used as an additive, sulphite-yeast masses are powdered and the hydrolysis industry waste waste collapseitis follows; its composition, wt.%:

The filler is a clay aggregate of a fraction of 3.5-5 mm. The preparation of the proposed polymer mixture is carried out as follows.

Into the concrete mixer they load in advance the dosed filler, aggregate, phosphogypsum, hydrolytic industry waste — spent collactivitis and fine dry PSB and mix for 2-3 minutes. Then the carbamide resin is injected and stirred again for 3-4 minutes until a homogeneous mass is obtained.

The prepared mixture is laid in molds, compacted for 1–2 minutes by vibration, and left for 1 day at room temperature. Then, to accelerate the curing process, the mixture in the forms is kept for 20 h in a heating chamber at. If necessary, the mixture can be cured at an ordinary temperature of 18 ° C and the design strength, identical to the heat-treated material, is achieved in 28-30 days.

Determination of the physicochemical properties of polymer concrete from the proposed and known mixtures is carried out according to standard methods. The results of the determination are shown in Table 2.
