Summary:The Fabric Reinforced Cementitious Matrix (FRCM) system in the last two decades was used to strengthen and rehabilitate historical masonry structures as an alternative of the well-known Fiber-Reinforced Polymer (FRP) system. The FRCM systems consist of different types of fiber in form of fabric mesh immersed in a cementitious/hydraulic or lime matrix; they present better compatibility with the substrate and less limitations in heritage applications. However, the durability and the interaction FRCM-substrate under the artificial aging mechanism in aggressive environment is not well known. The paper reports and discuss the first results of an experimental program planned to investigate the durability of some FRCM systems. The effects of the freeze/thaw and alkaline environment on both the mechanical properties of the FRCM coupons and the bond FRCM-to-masonry substrate were analyzed by the results of direct tensile and single-lap shear tests.
