CX) 05 O) O

The invention relates to construction materials, in particular, compositions of soil mixtures, reinforced with cement and organic additives, for the construction of bases and coatings of roads and aeromas.

The purpose of the invention is to increase the strength and reduce water absorption

Waste from the production of polyamide products is used in the form of chips, sawdust, scraps, crushed defective products, etc., previously dissolved in the cubic acid octaT of hporvil production.

The composition of the bottoms of the vinyl chloride production is as follows, wt.%: The desired fraction

1,2-Dichloroethane 21,2-87,3 Trichloroethane. 10.7-71.9 Tetrachloroethane Oh, 15-20.2 Light fraction

trans-dichloroethylene 0.13-1.3 1,1-dichloroethane 4.4-20.3 cis-dichloroethylene 1.9-5.2 benzene0.3-1.0

Chloroform1,4-4,3

1,2-Dichloroethane 65,5-87,3 Light volatile

factionsEverything else

Dp of dissolving waste from polyamide can be used both as tout, and light fraction.

Building mixture was prepared as follows.

Soil optimum moisture mixed with cement. Then in this mass was introduced pre-dissolved in the bottoms production

vinyl chloride waste from polyamide and thoroughly mixed until uniform. Samples — cylinders with a diameter and height of 50 mm — were molded from this mass, and compacted under a load of 15 MCa for 3 min.

Specific formulations of the proposed construction mixture and the mixture of the prototype are given in table. one.

Before testing, the samples were kept in a wet state for 28 days, and immediately before the test they were dried.

The test results are shown in Table. 2
