摘要
再生混凝土的应用,不仅能够减少废弃混凝土填埋导致的环境污染,而且能解决天然石料资源不足和废弃混凝土如何再利用的问题,其中,力学性能是再生混凝土研究领域的重要内容。对国内外再生混凝土力学性能的研究进展进行了总结,介绍了再生混凝土的抗压强度、抗拉强度、抗折强度、弹性模量、泊松比和应变的影响因素及其最新研究成果,并分析了目前研究的不足,以期为未来再生混凝土的研究提供新思路。
The application of recycled concrete can not only reduce the environmental pollution caused by waste concrete landfill,but also solve the problem of insufficient natural stone resources and reuse of waste concrete.Mechanical properties are an important part of the research field of recycled concrete.In this paper,the research progress of mechanical properties of recycled concrete at home and abroad was summarized.The influencing factors including compressive strength,tensile strength,flexural strength,elastic modulus,Poisson’s ratio and strain of recycled concrete and the latest research results were introduced.We also analyzed the shortcomings of the current researches,in order to provide novel ideas for the future research of recycled concrete.
