再生混凝土研究综述

Review of research on recycled concrete

介绍了建筑行业的发展现状和方向,从力学性能、基本构件、结构体系三方面阐述了国内外学者在再生混凝土方面的研究现状。综合分析表明,相对于普通混凝土而言,再生混凝土的抗压强度和弹性模量等降低10%左右,在基本构件及结构体系方面,具有一定的抗震性能,可满足一些次要结构的抗震设计要求。同时,再生混凝土原料来源于建筑垃圾,对建筑垃圾进行了再利用,降低了建设成本。因此,开展对再生混凝土的相关研究及应用,对发展绿色、生态、低碳的建设模式具有重要意义和前景。

The development status and direction of the construction industry are introduced in this paper, from three aspects of the mechanical properties, basic components, structural system, the research status of domestic and foreign scholars in the field of recycled concrete. Compre- hensive analysis show-s, compared with ordinary concrete, the compressive strength and elastic modulus of recycled concrete decreased by about 10%, in terms of basic components and structural systems, has a certain seismic performance, can meet some of the secondary structure of the seismic design requirements. Meanwhile, recycled concrete raw materials from construction waste, reuse of construction waste, reduce the cost of construction. Therefore, to carry out the research and application of recycled concrete, has great significance and prospects on the development of green, ecological, low carbon construction mode.
