Research on Interfacial Bonding Property of Modified Fiber Reinforced Concrete and Present Situation Analysis
Published 2022-01-01“…So far,scholars at home and abroad have done a lot of research to improve the bonding strength between the fiber and the matrix in concrete and ultimately to enhance the fiber reinforcement effect.This paper summarizes tests at home and abroad on the interfacial bonding property of fiber reinforced concrete and their evaluation indexes and analyzes the mechanism and the influence of the interfacial bonding property of modified fiber reinforced concrete from the two aspects of matrix property and fiber surface characteristics.It is concluded that nanomaterials,organic polymers,and part of the active minerals all affect the hydration process of cement concrete. The hydration evolution process,microstructure,and modification mechanism of the matrix in concrete under multi-mineral and polymer hybrid modification need to be studied immediately.Optimal modification methods for different fibers should be proposed according to economical efficiency,construction technology,and modification effect.…”
