Concrete and Composites Pedestrian Bridge
Steel reinforcing bars and tendons fulfill several requirements for reinforced concrete (RC) and prestressed concrete (PC), including strength, ductility, and bond to the concrete matrix. Steel bars are protected from corrosion when they are embedded in concrete because an extremely thin oxide layer forms on the surface and induces passivation. The protective passive film is promoted by the alkalinity of the solution present in the concrete pores. Passivity may be lost, however, when carbonation or a critical amount of chloride ions reach a bar's surface. Almost three decades after its first commercial applications, RC and PC construction with FRP reinforcement is finally at the dawn of widespread acceptance and use as perhaps the most suitable response to the durability challenges of concrete construction. The opportunities offered by composites are certainly not limited to improved durability; it can be argued that innovations in reinforcement forms, fabrication, and delivery can also elevate the quality, constructibility, and performance of concrete construction.
