纤维增强再生混凝土高温后力学性能研究进展
Research progress on mechanical properties of fiber reinforced recycled aggregate concrete after high temperature
摘要
Abstract
Recycled aggregate concrete is widely used in civil engineering because of its energy-saving,envi-ronmental protection and recycling.But because of its inherent defects such as low strength,the concrete structure being easy to burst after high temperature of fire,the way of adding fiber can be used to improve its mechanical properties after high temperature.Based on extensive literature review at home and abroad,the research results of mechanical properties of recycled aggregate concrete after high temperature by different fibers such as steel fiber,polypropylene fiber,basalt fiber,glass fiber and hybrid fiber are summarized,based on the theory of fiber reinforce-ment and the mechanism of deterioration and damage of concrete at high temperature.The effects of factors such as fiber type and content,temperature changes on the mechanical properties of fiber reinforced recycled concrete after high temperature,such as compressive strength,splitting tensile strength and elastic modulus of recycled concrete after high temperature,and the micro-mesoscopic mechanism of the reinforcement effect of different fibers on the matrix of recycled aggregate concrete after different high temperatures are analyzed.Finally,the current research is-sues and directions for further research are indicated.The reference for theoretical research and practical application of mechanical properties of fiber reinforced recycled aggregate concrete after high temperatures are provided.关键词
