Description

one

The invention relates to the production of building materials and can be used in the manufacture of supporting structures operating under the influence of highly corrosive mineralized waters.

Polymer-silicate mixtures based on liquid glass with mineral fillers, sodium silicofluoride and the addition of furyl alcohol and aniline hydrochloride 1 are known.

A disadvantage of the known mixtures is low water resistance.

Closest to the invention in its technical essence and the effect achieved is a polymer-silicate mixture comprising liquid glass 10.2-12.0%, sodium silicofluoride 1, 5-2, 3%, acid-resistant napoleum (andesite flour) 15-17% and aggregates - acid-resistant crushed stone 42-43% and sand 28-30% and organic additive in the form of furyl alcohol 0.18-0.43% and phenol-formaldehyde resin 0.12-0.3% 2.

The disadvantage of this polymer-silicate mixture is relatively low density, water resistance and large shrinkage.

The purpose of the invention is to increase the density, water resistance and reduce shrinkage.

This goal is achieved by the fact that a polymer-silicate mixture, including liquid glass, sodium silicofluoride, acid-resistant fillers and fillers, and organic pre-bacon, contains as an organic additive bottoms production of furyl alcohol in the following ratio of components, wt.

The improvement of the properties and structure of polymer-silicate concrete occurs due to the action of the hydroxyl and carboxyl groups contained in the bottoms of the production of furyl alcohol and cyclic radium with unsaturated bonds, which give a more uniform sorption

on the surface of the structural particles to the ghost. In addition, the addition of bottoms from the production of furyl alcohol has a stabilizing effect on liquid glass and prevents its early coagulation.

An example. A mixture of liquid -glass with the addition of bottoms of the production of furyl alcohol and separately a mixture of silica-refined sodium with finely dispersed, acid-resistant filler in the form of ground sand with a specific surface of 2500 cm / g is prepared. The prepared mixtures are combined and mixed, after which the acid-resistant sand aggregate is introduced into the resulting mixture with a grain size of 1.84 and the final mixing is performed. The preparation time of the polymer-silicate mixture is 4-5 minutes.

Mixture compositions for making samples are presented in c.

The proposed pstimersilicate mixture allows to obtain. Concrete more durable by 10-15%, with greater water resistance (an increase in the resistance coefficient by 6-10%) and 3-4 times with less shrinkage.

Samples are prepared from a polymer mixture with a vibration damping. After holding the prepared samples under normal conditions for a day, they are subjected to a dry heat treatment at 120 ° C for 12 hours.

The water resistance test was carried out in saline water, the composition of which is given in Table 2.

The test results of the samples are given in table.3.
