NEW TYPES OF COMPOSITE

Abstract

The polymer concrete properties are influenced by the components and also by the type of additions. The experimental studies realized on polymer concrete obtained of epoxy resin and aggregates have shown that components dosages, especially resin dosage, have an important contribution in obtaining high performance concretes. Different types of materials(waste, by-products, natural powders, etc.) can be introduced in the polymer concrete mixture for improving the properties or for obtaining new materials. The experimental results presented in the paper analyzed new composite polymers obtained by introducing in the mix different additions such as: silica fume, fly ash and tire powder. The resin dosage and addition quantity were maintained the same for all compositions (12.4% epoxy resin and 12.8% addition).The polymer concrete with fly ash shown good workability, a good microstructural compactity, the density of about 2,300kg/m and the highest value of compressive strength.
