The invention relates to the field of building materials, namely to the compositions of polymer concrete mixtures used to manufacture chemically resistant products and structures. The aim of the invention is to reduce costs, increase strength, frost resistance and water resistance. Polymer concrete contains, in parts by weight: epoxy resin 100, an oil-free fraction of a slate resin with a boiling point of 300-400 ° C 70-120, a distillation residue from a vacuum distillation of 3-dimethylaminopropanol with a boiling point of 88-119 ° C 15-25 and 340-440 mineral filler. The resulting polymer concrete is characterized by compressive strength of 116-125 MPa, cold resistance of 600 cycles, resistance coefficient after 6 months in drinking water of 0.95-0.97. 2 tab. |
