摘要：
The impact strength and durability of polyethylene terephthalate (PET) concrete were studied by orthogonal test. PET concrete was produced by mixing melted PET with aggregate and fly ash. The effects of three factors on the properties of PET concrete were investigated. The results showed that the most important factor was PET/AG, followed by sand ratio and PET/FA. The best mix proportion of PET concrete was PET/AG of 1: 3, sand ratio of 35% and PET/fly ash of 1: 1. The PET concrete has good impact strength than C30 cement concrete, lower than C50 cement concrete. Under 300 times freeze-thaw cycles, the weight of PET concrete loss slightly. The mass loss rate of PET concrete is less than 0.25%. The weight loss of PET concrete after test is less than 0.5%. The corrosion resistance coefficient of 30 times cycle is 90% and 60 times cycles is 75%.
