地震建筑废弃物资源化再生技术与对策研究
|
摘要
汶川大地震后,科学处理和再生建筑废弃物成为降低震后环境污染、节约骨料资源和开发新型材料的关键问题.遵从再使用、再利用和再循环建筑废弃物的原则,探讨了国外地震建筑废弃物的再利用与管理特点,分析了震后建筑废弃物资源化处理方法和用途,并剖析了就地取材骨料再生利用实例,包括混凝土的再生技术与性能和建筑废物砖的制作与性能,提出了建筑废弃物特殊化再利用的对策,应从清运管理、实施操作、低成本、无害化以及规定回收再利用率等方面开展,为灾区有效再生利用地震建筑废弃物提供了借鉴.
After Wenchuan earthquake,scientifical process,recycle and reuse of building demolition wastes become the key problems for decreasing environmental pollution,saving aggregate resources and exploiting new materials after earthquake.According to the reuse and recycle principles,the overseas management characteristics and ways on earthquake building demolition wastes are discussed.The treatment and application of recycling aggregate on the spot were analyzed,including reuse technology and capabilities of waste concretes as well as making and performances of waste bricks.The countermeasures such as conveyance,construction,cost,innocuous disposition and recycle ratio are put forward for further management.
