The results of an experimental investigation on the freeze-thaw durability of fiber reinforced concrete is presented. The primary objective of the research program was to determine whether the air content is the most significant parameter for the freeze-thaw resistance of fiber reinforced concrete, as is the case with normal concrete. Accordingly, air content in the mixtures was varied from 1. 2 percent to 10. 8 percent. The results indicate that air content is the most significant factor. Based on the results, it is recommended that at least 8. 0 percent air content should be specified for concrete structures exposed to severe freeze-thaw loading. Comparison of fiber reinforced concrete specimens with plain concrete specimens indicates that their behavior under freeze-thaw loading is essentially similar. For the same air content, freeze-thaw durability is the same for both plain and fiber reinforced concrete. An increase of cement content and a reduction of water-cement ratio improves the durability.
