建筑废弃物在道路工程中的再生利用研究
|
摘要
随着我国基础设施建设的发展,建筑废弃物的产生量迅速增长,对建筑废弃物在道路工程领域的应用指标要求与设计方法展开研究。针对不同再生骨料特点,通过试验对再生骨料混凝土、砂浆、水泥稳定再生基层的力学性能和收缩性能等进行了分析阐述,并提出了对应的再生集料合理掺量;研究成果进行了实体工程应用,并最终编制了深圳市地方标准《道路工程利用建筑废弃物技术规程》。
With the development of infrastructure construction in China, the output of building wastes increases rapidly. This paper studies the application index requirements and the design methods of building wastes in the road engineering field. Aiming at the characteristics of the different recycled aggregates, this paper analyzes and sets forth the mechanical properties and contraction performances of recycled aggregate concrete, mortar and cement stabilized recycled base, and puts forward the corresponding reasonable dosages of recycled aggregates.The study result is applied in the practical projects. Finally, the local standard of Shenzhen Technical Regulations for Utilization of Building Wastes in Road Engineering has been compiled.
