Abstract: Durability of concrete structures is one of the most significant problems currently facing the engineering community. The use of High Performance Fiber Reinforced Cementitious Composites (HPFRCC) may greatly enhance the durability and long term performance of concrete structures. However, prior to designing HPFRCC materials into practical applications, their durability performance must be shown equal or superior to concrete over long durations in service environments. In this article, the behavior under various environmental loads and the long term performance of a class of HPFRCC called Engineered Cementitious Composites (ECC) is summarized. This material is shown to have exceptional behavior under freeze-thaw cycles, hot-cold temperature cycles, carbonation exposure, fatigue loading, and long term mechanical performance. Additionally, results are presented of an ongoing two year comparison between ECC and concrete roadway patching applications on a Michigan Department of Transportation bridge deck.
