Results of tests on concrete specimens strengthened with the PBO-FRCM system made by PBO ( short of Polypara-phenilene-benzo-bisthiazole) fiber meshes embedded into a cementitious mortar (FRCM, Fiber Reinforced Cementitious Mortar) are presented and discussed in the papaer. tests were carried out varying both the bond length and the amount of the strengthening system. Obtained results furnish useful informations to determine the loss of bond between the PBO-FRCM system and the concrete, to define the failure modes and to evaluate the influence of mechanical amd geometrical parameters on the loss of bond PBO-FRCM-to-concrete. A comparison between experimental results and theoretical predictions of the bond-slip law PBO-FRCM-to-concrete is, then, presented and discussed
