建筑固体废弃物再生骨料的分类及其物理性能研究

我国的城市建设和旧城改造每年都要产生大量的建筑固体废弃物，处理和堆放这类建筑固体废弃物，不仅要花费较多的资金，而且还严重影响环境。将建筑固体废弃物回收利用符合我国的可持续发展战略，并有着社会、经济、环境多种效益。本文对再生骨料的表观密度、吸水率、压碎指标等物理性能进行试验和分析。并对再生骨料的利用提出建议，以期实现建筑固体废弃物的“零排放”以及全部资源化。

Study on building waste recycled aggregates classifying and its physical characteristics

Large quantity of building solid waste is produced every year, and the disposal and stockpiling of these wastes has become a severe social and environmental problem in the territory, so recycling of these wastes, which has social, economic, environmental benefits, is becoming more and more important. The recycling and the appli-cation of recycled aggregates not only resolve the numerous heaped construction and demolition (C&D) wastes, but also provide a method to resolve a serial of problem. Study on physical characteristics of building waste recy-cled aggregates about apparent desity, water absorpotion, cmshing index value. Some key problems about recycled aggregates utilization are put up, for its resources circulation utilization.
