Abstract: Textile-reinforced concrete (TRC) has great potential for application in structures exposed to severe mechanical or environmental loading. This paper presents an overview of the cur-rent knowledge on the durability of this composite and its components. An additional focus is centred on the protection of steel reinforcement as in the case of the strengthening or repair of RC structures using TRC. In doing this, transport properties in the cracked state, long-term tensile strength and strain capacity, and resistance to aggressive environments have been identified as critical parameters. Current knowledge indicates that TRC can exhibit high long-term mechanical performance and favourable transport properties in the cracked state. While also a superior resistance of TRC to aggressive environments may be expected, as compared to ordinary concrete, there is little information available on the effects of aggressive environments on the mechanical properties of the material. To be able to utilise the superior qualities of TRC fully, it will be necessary to develop a realistic and reliable performance-based durability design concept for structures made of or strengthened by TRC. The article at hand provides a framework for such durability design.
