In this discussion of corrosion resistant reinforcement, two approaches are considered: the use of epoxy coated reinforcement, and the replacement of conventional steel with non-ferrous reinforcement. Epoxy coating consists of a layer of epoxy fusion-bonded to the surface of a conventional reinforcing bar. The thickness of the coating is critical. The production of coated bars and its handling are discussed, as well as the costs and problems encountered with it. Non-ferrous reinforcement discussed here include fiberglass reinforced plastic rebar with tensile strength similar to that of high yield steel but with a third of the modulus. Prestressing tendons of glass fiber are discussed, as well as the building of two full scale bridges in West Berlin and Dusseldorf, West Germany. The bridges include a novel form of monitoring using fiber optics and copper wire sensors, which allows the stress in the tendon to be checked at any time. The use of tensar polymer grids is discussed.
