ABSTRACT
Aggressive environmental conditions as moisture, temperature and presence of salts, may affect the interfacial behaviour of Fabric Reinforced Cementitious Matrix (FRCM) bonded to masonry. Studies on characterization of FRCM using various types of fibers and cementitious matrices applied on masonry substrates made of bricks having different compressive strengths showed the occurrence of the various failure modes under pull-off actions, and the reflecting of a good bond in correspondence of higher brick strength. Strengthening and repair of existing masonry structures is a topical issue, particularly in seismic area, where vulnerabilities may emphasize severe damage or collapse. Among more traditional or modern techniques, composite materials made of fibrous fabrics embedded in several types of matrices, are increasingly adopted, due to their quite easy application, corrosion, immunity, high strength-weight ratio and feasibility. They are also proposed in historical structure context where, nevertheless, sustainability, compatibility, durability and removability, should also be attained.
