中文摘要：
近年来，我国城市化进程的推进和新农村建设的发展，不但使得国家能源负担日益加重，而且还随之产生了大量的建筑废弃物需进行处理，这些建筑废弃物已在城市固体垃圾中占有了一个相当大的比例，并且还在不断增长当中。对此，我国政府越来越重视节能和资源的回收利用问题，大力提倡和发展建筑废弃物的再利用。再生混凝土和再生砂浆作为新型的节约型建筑材料，对于保护环境、节约资源、发展生态建筑具有重要意义，近年来国内外学者开展了相关研究，并取得一定成果。本文通过分析再生混凝土、再生砂浆等主要再生建筑废弃物的力学性能及其破坏机理，以期为再生废弃物的进一步深入研究和应用提供更完善的科学依据。
英文摘要：
In recent years, as Chings urbanization process and promote the development of new rural construction, not only makes the increasing burden of energy and also subsequently generated a lot of construction waste, the construction waste occupies a significant proportion in municipal solid waste, and is still growing. In this regard, our government＇s increasing emphasis on energy conservation and resource recycling, advocate and develop the construction waste recycling. Recycled concrete and recycled mortar as new saving building materials, has important significance for the protection of the environment, conserve resources, development of eco--building, domestic and foreign scholars carried out researches and achieved certain results in recent years. This paper analyzes mechanical properties and failure mechanisms of various recycled concrete, recycled mortar and other recycled building waste, get a view to regeneration of waste further study and application provide a scientific basis.
