Description

1 The invention relates to building materials, namely to the composition of the polymer concrete mix. A known polymer concrete mixture f includes, wt.%: Epoxy oligomer 3-6, coal tar 69, quartz sand 42-44, granite 42/43 plating, polyethylene polyamine 0.8-2 and aromatic solvent 1-2, Closest to the proposed Technical essence and achievable result is polymer concrete, including May,%: Epoxy oligomer 2.1-18.3 Vinyl monomer 9.3-21.3 Aminesh hardener 0.8-2.2 Pigment 0.69-2.29 Peroxide or hydroperoxide ini0, 6-1.3 cyator Tertiary amine from the group of low molecular weight 11, 6-13.6 ln of rubbers Acid-resistant Osta Disadvantages of known noe filler mixtures is relatively low so forth NOSTA tensile, high elongation at razryue and a short time before the concrete breaking under load of 7.5 MPa .vode This aim is achieved

The fact that polymer mixture, including epoxy resin, polyethylene polyamine and quartz sand, additionally contains coal tar, polymethylsilazane, ethyl silicate and quartz flour in the following ratio, wt.% Epoxy resin 12-15 Polyethylene resin 1.8-2.0 Coal tar 10-12 Polymethylsilane 0.4-0.6 Ethyl silicate 0.7-0.9

To determine the properties of the polymer concrete, samples are made from the mixtures shown in Table 1. Manufactured samples are cured in the laboratory for 24 hours, after which they are thermostatic for 14 hours. The results are shown in Table 2,. The proposed polymer concrete mixture can be used in the repair and monolithing of reinforced concrete structures of hydroconstructions, for the manufacture of elements of building structures that are used in water under load, in making chemical coatings for floors, roads and airfields.
