中文摘要:相比于天然骨料混凝土,再生骨料混凝土的强度和弹性模量有所下降,脆性增加,利用纤维增强再生骨料混凝土的力学性能是再生骨料混凝土改性的重要途径之一。综述了不同类型纤维和其掺量对再生骨料混凝土强度、弹性模量、阻尼、抗冲击和抗疲劳等力学性能的影响和工程应用,总结了纤维增强再生骨料混凝土力学性能的机理,并提出了纤维再生骨料混凝土有待进一步研究的问题。现有文献表明纤维可以有效提高再生骨料混凝土的力学性能。
外文摘要:Compared with natural aggregate concrete(NAC),the strength and elastic modulus of recycled aggregate concrete(RAC)generally decrease and the brittleness increases.Adding fiber to concrete is one of important methodologies to improve the RAC mechanical properties.The effects of fiber types and contents on the engineering application and RAC mechanical properties,such as strength,modulus of elasticity,damping,impact resistance and fatigue resistance are summarized.Then the fiber improvement mechanism of RAC mechanical properties is analyzed.Finally,some significant problems on the further investigation of mechanical properties and improvement mechanics of fiber reinforced recycled aggregate concrete(FRAC)are proposed.The existing literatures show that fiber can effectively enhance the RAC mechanical properties.
