再生塑料混凝土研究现状

Research status of recycled PET concrete

近几年随着世界各国塑料制品消费量大幅增长,产生的大量塑料废弃物亟待处理。由于其经济和生态优势,将废弃塑料回收处理后掺入砂浆或混凝土中已成为解决塑料废弃物的最佳方案之一。综合国内外文献,介绍了混凝土用塑料类型及其相关处理方法,并介绍了塑料掺入对混凝土物理性能、力学性能、耐久性能影响的国内外研究现状。

In recent years,the substantial consumption growth in plastics in the world leads to a huge amount of waste plastics which need urgent treatment.Due to its economic and ecological advantages ,the waste plastics recycling and incorporation in mortar or concrete has become one of the best solution to solve the plastic waste problem.Through the study of the references at home and abroad, it discussed the plastic type and associated processing methods and reviewed the research status of physical performance,mechanical properties and durability.
