摘要
采用纤维对再生混凝土进行增强改性形成纤维增强再生混凝土,可在一定程度上弥补再生混凝土的天然缺陷,对保护自然环境具有重要意义。为进一步推动纤维增强再生混凝土的发展及应用,本文在大量查阅国内外文献的基础上,对现阶段纤维增强再生混凝土力学性能的研究成果进行深入归纳总结。重点阐述不同种类纤维对再生混凝土常温下基本力学性能、高温下基本力学性能及动力学性能的增强效果与影响规律,指出了纤维再生混凝土力学性能研究有待进一步解决的问题,并提出了相关研究建议及展望,为该领域的深入研究及纤维再生混凝土的推广应用提供参考。
Fiber-reinforced recycled concrete is formed by adding fibers into the recycled concrete,which makes up for the natural defects of recycled concrete to a certain extent and is of great significance in protecting the natural environment.In order to further promote the development and application of fiber-reinforced recycled concrete,based on a large number of references at home and abroad,the research results of mechanical properties of fiber-reinforced recycled concrete are summarized.This paper focuses on the reinforcement effect and influence law of different kinds of fibers on the basic mechanical properties of recycled concrete at room temperature,at high temperature and dynamic properties,points out the problems to be solved in the research on mechanical properties of fiber-reinforced recycled concrete,and puts forward the research suggestions and prospects,so as to provide reference for the further research in this field and the popularization and application of fiber-reinforced recycled concrete.
