Sažetak
During the long history of unreinforced masonry (URM), strengthening moved from traditional methods and techniques to modern materials and methods. The traditional techniques indicated several disadvantages in the sense of reducing the available space, impact on the architectural value of the structure, possibilities of corrosion due to environmental impact, and similar. For quite a while fiber- reinforced polymers (FRP) were used for strengthening of masonry structures ; however, its application was relatively limited. Thought out the time FRP materials showed their advantages and disadvantages. A new generation of composite systems was developed with the cementitious matrix called fabric-reinforced cementitious matrix (FRCM). FRCM composites are a newly developed strengthening system that was first used for strengthening of concrete structure that consists of high-strength fibers embedded in a cementitious grout and externally bonded to the substrate. This paper aims to give a state-of-the-art of the new FRCM methods, compare different experimental studies, and give a parametric index of the various methods. The effectiveness of the strengthening procedure is related to the unconfined element’s load-bearing capacity.
