Abstract：Glass fiber bead chain addition way is adopted in order to solve the problem of poor interfacial adhesion of fiber reinforced mortar,stress concentration at both ends of fiber and the resulting two-phase slip. Glass fiber depends on the method of making bead chains by adding epoxy resin onto long fibers to reinforce mortar. It makes the embedded effect between the fiber bead and the concrete to form structural constraint. Microcosmic test showed that the caking property between the two phases was very poor. The properties of chopped glass fiber reinforced mortar and glass fiber bead chain reinforced mortar are compared,result show that glass fiber bead chain addition way avoids the disadvantages of poor interfacial bonding between the two phases,it solves the problem that work performance is poor and mechanical performance improvement is not obvious or even lower after the addition of large amount of chopped glass fiber. It has good mechanical properties.
