Characterisation of polymer concrete with epoxy polyurethane acryl matrix

摘要

This paper studies a new type of polymer concrete obtained using epoxy polyurethane acryl and aggregates. Mechanical properties, such as: compressive strength, flexura! strength, elasticity modulus, pull-out stress and adherence stress between cement concrete and polymer concrete were experimentally determined. Thermo-physical properties, such as: bulk density in natural and dry state, relative and absolute mass humidity, thermal conductivity, linear thermal dilatation, thermal shock strength, chemical resistance, frost-thaw resistance and water adsorption resistance were studied to establish the durability properties of the epoxy polyurethane acryl concrete. The experimental results have shown that epoxy polyurethane acryl concrete is a high performance, lightweight concrete with properties that recommend it as a possible replacement material for classical building materials.
