Description

one

The invention relates to the field of building materials, in particular, to compositions based on mineral B -: aggregate, aggregate, water and a modifying polymer additive for the manufacture of mortars or concretes.

Mortar can be used in the installation of waterproofing structures and plaster, concrete mix - for the manufacture of concrete and concrete products.

The known composition of the concrete mix, including, wt.%:

Cement

20-40

35-6O filler

Disodium salt

monoether sulfonic, 01-O, 25

succinic acid

Scrubber paste

The closest to the invention to the technical essence and the achieved result is the composition of the concrete mix. si, including portland cement, filler, body, water and polymer additive, as a polymer additive, the concrete mixture contains an aqueous dispersion of styrene copolymer, 2 - ethyl hexyl acrylate and acrylic acid in the amount of 1.5-2.7% of the weight of portland cement (in terms of dry matter).

However, concrete; made from a known mixture, does not have high enough strength characteristics and frost resistance.

The aim of the invention is to increase the strength characteristics and frost resistance of mortar or concrete.

This is achieved by the fact that the composition for the manufacture of mortar or concrete, including mineral reinforcing, mineral aggregate, polymer additive and water, contains, as a full-dimensional additive, the product of purification of external water produced by acrylonitrile butyrene plastic at the following ratio of components in weight parts x: Mineral in suspect SOW Mineral filler 50-500 Wastewater treatment product produced by acrylon {trilbutadiene; 3-90 la-ioo washing hex. Acrylonitrile-butadiene-styrene wastewater treatment product; Plastic content in wt.%: Acrylonitrile-butadiene-styrene copolymer 15-25 Gvdrat alumina 5-15 Wood flour 5-15 WaterEverything The building composition is prepared in the following way: the mineral is mixed with the aggregate in appropriate proportions and add mixing water with pre-introduced waste. The components are mixed in a conventional type paddle mixer. Mix components for 10-20 min4 until a homogeneous mass without lumps and impurities. . The composition of the composition is shown in Table 1. Comparative physicomechanical characteristics of the compositions proposed and known are listed in Table 2. The use of the waste water cleaning product also solves the problem of waste disposal, which makes it possible to abandon the construction of facilities to prevent environmental pollution. Table 1
