Abstract

The invention relates to the field of building materials and is aimed at increasing the strength of polymer concrete. Polymer concrete mixture contains waste of production of recycled acetate based on cellulose acetate 28-38%, grinding waste of glass production 37-57%, acid slag of iron and foundry production 15-25%. The above acidic slag is introduced into the polymer-concrete mixture in the form of fractions 5-10 mm and 10-15 mm at a ratio of 2: 1. 1 hp f-ly, 2 tab.

As a starting component for the proposed polymer mixture, waste from the production of secondary acetate is used, which is formed at artificial fiber plants during the filtration process (filter clogging), of the following composition, wt%: cellulose acetate 25.4; acetone 71.1; titanium dioxide 0.53; SiOg impurities and undissolved cellulose 0.50; water the rest. Grinding waste is used as a filler.

The polymer concrete preparation technology is as follows.

. In the mixer, the natural waste from the production of secondary acetate is mixed with the air-dried state-grinding grinding waste to obtain a homogeneous mass. Then coarse aggregate — sour slag, previously crushed to a fractional composition of 5–10 and 10–15 mm at a 2: 1 ratio, is introduced into the mass. The mixture is thoroughly mixed until a uniform distribution of slag (2-3 min). Prepared mass by plastic casting After cubic hardening in natural conditions, the samples are molded and after 28 days at room temperature to ensure the separation of acetone from the waste of the production of secondary acetate ( otsess can be accelerated by heating at until no odor of acetone) is determined by their properties "

Hardening of this concrete mixture occurs without the introduction of catalysts and hardeners due to the random gradual polycondensation of cellulose acetate, which is contained in the waste production of secondary acetate.

The physicomechanical characteristics of polymer concrete samples prepared from the proposed and known polymer concrete mixtures are listed in Table 2.
