Polymer concrete and processes for the production of polymer concrete

Abstract

Polymer concrete as a material consisting of fillers, a binder, and a hardener, wherein the weight fraction of the fillers is between 75% and 95%, the weight fraction of the vegetable oil or natural resin is between 3% and 18%, and the weight fraction of the hardener is between 2% and 15%, wherein the fillers comprise quartz flour with a weight fraction of 10% to 20%, sand with a grain size of 0 mm to 2 mm and a weight fraction of 20% to 30%, gravel with a grain size of 2 mm to 8 mm and a weight fraction of 30% to 40%, and gravel with a grain size of 8 mm to 16 mm and a weight fraction of 20% to 40%, characterized in that the binder consists of chemically modified vegetable oil or chemically modified natural resin, wherein the binder is triglycerides from vegetable oil or terpenes from natural resin, preferably from rosin. are modified to acrylates or polyols or epoxy resins or polyesters, wherein modified polyols are hardened by the addition of isocyanates or polyisocyanates, and / or wherein polyesters are hardened by the addition of polyols and / or wherein native acrylates or native unsaturated polyesters are polymerized by radicals.
