摘要：

采用废旧PET塑料瓶作胶结料来制备塑料砂浆。研究了不同的PET与砂的比例、养生时间以及少量沥青的添加对塑料砂浆的物理和力学性质的影响。试验结果表明,塑料砂浆具备吸水率低,强度增长迅速的特性。随着塑料砂浆中含砂量的增加,其抗压强度与抗折强度增大。在室温条件下,塑料砂浆养生3h即可达到最终强度的90％以上;养生24h可达到最终强度。在塑料砂浆中加入少量的沥青,能够有效提高塑料砂浆的抗弯拉性能。

关键词: 废旧PET瓶, 塑料砂浆, 抗压强度, 抗折强度

Abstract:

A simple and effective method to recycle waste polyethylene terephthalate (PET) bottles to produce plastic mortar was discussed. The effects of PET-to-sand ratio, curing time, and addition of asphalt on physical and mechanical properties of plastic mortar were investigated. According to the results, plastic mortar had the characteristics of low water absorption and fast strength growth. As the sand content increased, the compressive and flexural strength of plastic mortar increased. At the room temperature, plastic mortar could attain over 90％ of its ultimate compressive strength within 3 hours. Adding a small amount of asphalt could improve the plastic mortar’s flexural strength.

Key words: waste polyethylene terephthalate bottles, plastic mortar, compressive strength, flexural strength
