The invention relates to the production of building materials for the manufacture of chemically resistant products and structures. The aim of the invention is to adjust the specific toughness. Polymer concrete mix includes, wt%: water-soluble carbamide resin 8-9.5, sand 26.1-26.4, ground andesite 10-12.5, sulfonated zanolamine formaldehyde resin 0.2-0.4; zipichlorohydrin rubber 0.4-0.5; granite rubble the rest. The resulting polymer concrete has a specific impact strength of up to 0.4 J / cm. 2 tab. |
