Textile reinforced concrete offers a new innovative technology to strengthen or repair concrete structures with thin layered composites of fine grained concrete and fabrics of high strength glass fibers or multi filament roving respectively. Regarding the structural behavior, different mechanisms of bond play an essential role. These bond mechanisms are discussed with some details, considering experimental investigation, mechanical and numerical models and some numerical calculations.Regarding strengthening or repair of existing concrete structures it may be highly desirable to have very thin additional load carrying layers applied to structures. This cannot be realized with steel reinforcement, as steel rebars require an additional layer width of at least roughly 5 cm.
