Durability of concrete in a marine environment is a function of its mixture constituents, freeze-thaw susceptibility, abrasion resistance, fatigue strength, and corrosion of embedded metal. These problems usually manifest themselves in the tidal and splash zones of a structure. Fiber reinforced concrete has been shown to have improved fatigue characteristics and improved cracking behavior over conventional concrete. These properties can be advantageously applied to concrete in a marine environment, providing the durability in that environment is satisfactory. Paper describes a large number of both laboratory and field tests of fiber reinforced concrete, subjected to a severe exposure environment, that have been conducted over the last 20 years. Field tests in both severe and mild marine environments are included. Performance data and mixture information from these studies is provided
