废弃混凝土回收与二次利用技术

Waste Concrete Recycling and Reuse Technology

传统的处理方法是堆放或填埋,不仅占用了大量耕地,而且会造成环境污染,虽然我国对再生混凝土的研究起步较晚,还处在试验室阶段,但也取得了相应的成果,根据废弃混凝土污染源点拌和站收集利用效果分析,详细介绍了废弃混凝土回收处理工艺流程以及分析了搅拌运输车拌和清洗回收砂石的经济效益。

The traditional treatment of waste concrete is stacking or landfilling.This not only occupies a large amount of cultivated land,but also pollutes the environment.Although the research on recycled concrete started late in China and is still in the laboratory stage,corresponding achievements have been achieved.According to the analysis of collection and utilization effect of point mixing station of waste concrete pollution source,this paper describes the process flow of waste concrete recovery and treatment in detail,and analyses the economic benefits of mixing and cleaning sand recovered by mixing transporter.
