摘　　要：近年来,再生骨料在工程中的应用逐渐普遍化,其能够缓解我国资源不足的压力,减少我国的环境污染问题。然而,再生骨料相对天然骨料在力学性能上较差,因此在工程应用领域还比较局限。为了拓展再生骨料混凝土的应用领域,首先需要对再生骨料进行增强处理从而提高其力学性能。考虑到再生混凝土应用的可靠性、安全性与长远性,本文对再生骨料的增强处理方法和再生混凝土的耐久性进行了相关介绍,以期可在再生骨料力学性能增强的基础上,为今后研究人员对其进行耐久性性能研究提供参考,并进一步开拓再生骨料混凝土的应用领域。In recent years,the application of recycled aggregate in engineering has been gradually popularized,which can alleviate the pressure of insufficient resources and reduce the environmental pollution problem in China.However,the mechanical properties of recycled aggregate are worse than those of natural aggregate,so its application in engineering is still limited.In order to expand the application field of recycled aggregate concrete,it is necessary to strengthen recycled aggregate to improve its mechanical properties.Considering the reliability,safety and long-term application of recycled concrete,the strengthening treatment methods of recycled aggregate and the durability of recycled concrete are introduced in this paper.Based on the enhancement of mechanical properties of recycled aggregate,it is expected to provide reference for researchers to study its durability in the future,and further explore the application field of recycled aggregate concrete.
