Sumario:NSM strengthening technique under the influence of temperature and relative humidity, in which the interaction between materials involved is analyzed, is studied in this PhD. Therefore, this work is aimed at contributing to a better knowledge about short – term bond behaviour of NSM Carbon FRP (CFRP) bars reinforcement Systems. The influence of temperature and relative humidity on the short-term bond behavior is analysed and an analytical model, based on the fracture mechanical apporach to determine bond toughness according to the failure mode, is developed. To achieve the goal, an experimental campaign with two series has been carried out. Single shear pull-out concrete blocs strengthened with NSM CFRP bars have been conducted. The experimental results of experimental test campaign, together with the application of development analytical model, are used to characterize the fracture bond behavior
