Unsaturated polyester resin concrete: A review

Abstract The scope of this paper is to provide a systematic review of the main influencing factors of unsaturated polyester resin concrete (UPC), including the unsaturated polyester resins (UP), aggregates (recycled aggregates), fillers, fiber, methyl methacrylate (MMA), the curing temperature, and humidity, curing age. The corrosion resistance and related mechanical properties of UPC are better than OPC. But the shrinkage of UP during curing may cause internal stress and shrinkage problems in UPC. With the emphasis on the environment, the feasibility of recycled polyethylene terephthalate plastic (PET) in the preparation of regenerated unsaturated polyester resin concrete was discussed. Researches on green vegetation and permeable pavement using the UPC has also shown that UPC has unparalleled advantages compared to ordinary Portland concrete (OPC) and asphalt concrete.
