摘    要:根据研究文献,总结了再生混凝土的技术和发展,主要包括再生混凝土的物理性能、力学性能、耐久性、配合比设计、结构性能和造价分析.结果表明,废弃混凝土的再生利用是可行的,可以用于土木工程的非承重构件和某些承重构件中.与普通混凝土相比,再生混凝土在配合比设计、材料性能及结构性能等方面均存在一定差异,需要进行专门研究.此外,还讨论了混凝土中骨料与水泥石之间界面层形成机理、基本特征和可能的强化措施,为再生混凝土的工程应用提供一定的参考.最后,结合国家的可持续发展战略,提出了再生混凝土技术开发需要进一步研究的问题.

关 键 词:再生骨料  再生混凝土  力学性能  耐久性  造价分析

Abstract:The technology and development of recycled concrete are summarized in this paper based on the research literature. It mainly includes the physical properties, mechanical properties, durability, mix design, structural behavior and cost analysis of recycled concrete. From these results, it is shown that recycling waste concrete is feasible as self-bearing members and some load-bearing members in civil engineering. Compared with normal concrete, recycled concrete is somewhat different in its mix design, material properties and structural behavior, which requires a particular study. In addition, the formation mechanism, basic characteristics and reinforcing measures of interfacial transition zones between the aggregates and cement paste of concrete are discussed, which provides a certain reference for engineering applications of recycled concrete. Finally, some problems that need to be further studied for the technological development of recycled concrete are proposed in combination with the sustainable development strategy of our country.
Keywords:recycled aggregate  recycled concrete  mechanical properties  durability  cost analysis
