Degradation of Metal-Fiber-Reinforced Concrete Exposed to a Marine Environment

Source

The object of this research was to determine the effects of a marine environment on the integrity of metal-fiber-reinforced concrete. Metal-fiber-reinforced concrete has potential for uses in marine structures where the metal fiber may introduce tensile strength, abrasion resistance, and fatigue properties which may justify the added cost when compared with conventional concrete. Metal-fiber-reinforced concrete specimens were tested in flowing seawater and freshwater laboratory exposures. Comparisons were made to specimens exposed in the tidal zone of Narragansett Bay. Freeze-thaw experiments were also conducted. Results were obtained using standard and modified ASTM testing procedures as well as electrochemical corrosion rate monitoring techniques. The results indicate that stainless steel fibers are needed in marine applications.
