Abstract: Fabric reinforced cementitious matrix (FRCM) gains its importance to strengthen masonry buildings against earthquake. Mineral or plastic based continuous fibers reinforce a cementitious matrix. Polymer, glass and basalt fabrics reinforce the cementitious mortar. Engineers have been using FRCMs to strengthen masonry historical buildings during last decade. Considering the restrictions in the historical buildings, a lime based matrix is preferred. Experimental study executed with FRCM systems is the scope of this research. Glass and a hybrid of glass and polypropylene fabrics were employed as reinforcement. FRCMs have been used as cementitious composites for years. Utilization of mineral based continuous fibers is comparatively new application. Researches on this topic are proceeding in the literature. Similar contributions such as improving strength and toughness are expected. Experimental study executed. Composites designed and produced. Binder was hydraulic lime. Bending and tensile tests executed on lime composites. Flexural, tensile strength and toughness values of composites were determined. Pull off performance of the composites on brick masonry wall was obtained as well. The main conclusion can be summarized as follows: Beyond fiber amount inside, fabric design effects the mechanical performance of the composite. The numbers of layers are effective at tensile test while they do not influence flexural properties significantly.
