Fabric-reinforced cementitious matrix (FRCM) is a safe, durable, and convenient alternative to fiber-reinforced polymer (FRP) for the strengthening of concrete or masonry structures. However, the nonuniform bonding between mortar and fabric leads to the pullout-fracture failure of fiber bundles, and bond failure at the FRCM/concrete or fabric/mortar interface, resulting in high uncertainty in mechanical performance，which is one of the critical factors affecting the efficiency of FRCM and its application. This paper summarizes the existing measures to improve the performance of FRCM and FRCM-strengthening from the material, interface, and member levels, respectively. Meanwhile, the corresponding mechanisms, merits, and weaknesses of each measure are discussed. We found that increasing the interface performance between the fiber bundles and mortar, or between the FRCM and concrete alone does not necessarily guarantee the improvement in the mechanical properties of the FRCM and FRCM strengthened members. The most promising method to ensure efficiency is to improve them simultaneously. Therefore, a simple, fast, and efficient method for improving the bonding properties of the fiber–mortar interface to enhance the performance of the FRCM plate remains to be investigated. The clarification of the effect of anchorage on the FRCM/concrete interfacial properties and FRCM-strengthened members are key scientific issues that require further investigations.
