Abstract (EN): There are many different factors influencing the durability of the bond technique applied to concrete structures: the state of the used concrete as well as the surface preparation of its substrates, the quality of the FRP application and the FRP itself, the durability of the resin and especially important is the aging effect. There are many different aspects of influence, such as temperature, humidity, UV-light, alkalinity, corrosion, and fatigue. Both humidity and temperature are the most important environmental factors of influence for this work as they might be critical for the durability and resistance of the interface between FRP and concrete in the long-term behaviour. This paper presents the results of testing the effect and influence of temperature and humidity in the interface between carbon fibre reinforced plastics (CFRP) and concrete substrates through out using seven concrete specimens reinforced with externally bonded unidirectional CFRP sheets or laminates by the Pull-off test method. The results were presented and discussed in terms of ultimate adhesion strength of the interface between concrete and CFRP with regard to environmental conditions.
