The Application of Recycled Epoxy Plastic Sheets Waste to Replace Concrete in Urban Construction and Building

Abstract

Epoxy plastic, a form of epoxy resin, is widely employed in a variety of sectors due to its superior mechanical qualities and adaptability. The application of waste epoxy plastic in urban highway construction has been a major topic of study. To conduct this study, epoxy polymers are mixed with concrete to enhance the thermal and compressive resistance and tensile strength, which acts as a substitute for conventional cements. The experimental results indicate that ER concrete has good cohesive qualities since it does not collapse or peel, and the nature of the epoxy plastic guarantees that ER concrete has great mechanical capabilities due to the strong bond between the epoxy resin and the fibres. In terms of frost resistance, granular concrete with a 10% ER additive has a mass loss rate between 0.3% and 0.12% and a strength loss rate between 3.55 and 9.4%, outperforming conventional concrete. When often loaded by traffic, ER concrete exhibits no substantial permanent deformation, and its fatigue damage rate is superior to that of ordinary concrete. In total, 10% admixture of ER concrete may efficiently fulfil BPN (British Pendulum Number) and structural depth standards, while greatly improving the road’s skid resistance. In addition, its modulus of elasticity, deformation capacity, and high-temperature stability are superior to those of conventional concrete.
