再生纤维增强混凝土的应用研究OACSTPCD

Based on the concept of circular economy,recycled fiber,as a concrete reinforcement material can effectively reduce the cost and increase the utilization efficiency of resources while enhancing the mechanical properties,crack resistance,durability and other characteristics of concrete.This paper analyzes the research status of recycled fiber reinforced concrete in China,and studies the recycling sources,material properties and application effects of recycled steel fiber,recycled plastic fiber,recycled glass fiber and recycled carbon fiber in concrete.The results show that the recycled fiber reinforced concrete have good properties and have great potential as substitutes for common fiber reinforcement materials in the future.
