| 摘 要： | 再生混凝土是再生利用废弃混凝土的一种新材料，具有显著的环境保护和经济利益优势，是实现建筑、资源、环境可持续发展的主要措施之一。特别是汶川大地震后，产生的建筑垃圾远远超过了我国年产建筑垃圾总量，给地震灾区的重建工作带来了巨大的挑战。本文结合国内外再生混凝土研究发展现状，介绍了再生混凝土的基本性能和其在结构应用中的表现；同时，结合组合结构的优势，探讨了钢管再生混凝土构件的力学性能和再生混凝土在钢管组合结构中的应用前景。提出在灾后重建工作中，我国发展再生混凝土研究和应用的必要性和可行性。

| Abstract: | Recycled aggregate concrete is a kind of new material which recycles waste concrete with the significant advantages of environmental protection and economic benefit, as a main measurement to realize the sustainable development of construction, resource and environment. Especially after Wenchuan earthquake, tons of construction waste have been produced with the amount far surpass the annual production of construction waste in China, resulting in a great challenge of reconstruction to the quake area. In this paper, the basic properties of recycled aggregate concrete and its application performances in structures are presented according to the current research achievements from home and abroad. Meanwhile, the mechanical performances of recycled aggregate concrete-filled steel tubes and the application outlook of recycled aggregate concrete used in steel tube composite structures are discussed taking the superiorities of composite structure into account. Furthermore, the necessity and feasibility to promote the research and application of recycled aggregate concrete during the post-earthquake reconstruction in China are proposed. |
