In recent years, fibre-reinforced polymers (FRP), and glass-fibre reinforced polymers (GFRP) in particular, are advocated to be a promising alternative to traditional steel reinforcement in concrete structures to alleviate corrosion-related problems. Despite a large amount of studies on the short-term performance of FRP as non-prestressed reinforcement in concrete structures, there exists a lack of methods and experimental data to predict the durability of FRP-reinforcement. The investigation of the long-term behaviour is very extensive and complex due to the high effort and the long test duration. Furthermore, the occurring degradation and failure mechanism of FRP reinforcement in the real installation situation are largely unknown.
