Abstract:
The future of prestressing reinforcement for both steel and fiber-reinforced polymers (FRP) tendons is challenging both technically and in application. The market and the need exists for improved prestressing tendons. Improvement in even well-proven steel tendons are likely and, in FRP tendons, even more likely. Prestressing reinforcement history, usage, corrosion behavior and protection are discussed. Possible innovations in the New Millennium such as higher strength tendons, more corrosion resisting tendon systems, coated tendons, inherently more corrosion resisting steels and FRP systems are presented.
