Abstract

Construction engineering history may have reached a new stage with the advent and availability of the new, low-cost, high-performance structural composites. Not only the fiber reinforced plastic (FRP) ‘pultruded’ sections can replace steel in many load bearing structures, but strengthening of concrete beams with internally or externally bonded fiber-reinforced plastics (FRP) has also been proved feasible to increase the load carrying capacity and stiffness of existing structures. Composites made with glass, aramid, or carbon fibers are being increasingly considered for pre-tensioning, post-tensioning, or reinforcing concrete. To replace the corroding steel rebars, FRP system may eventually be used in concrete bridge decks or other outdoor concrete flooring structures. However, quantitative guidelines for applications of composites in structures or reinforcement of concrete are not available. This paper reviews the current state of composite applications in infrastructure including concrete reinforcement and focuses on the R&D thrusts the lack of which appears to be hindering the development of the quantitative guidelines.
