The report is divided into three sections: 1. The physical properties of FRC; 2. The areas where concrete durability is affected by the addition of fibers; and 3. A series of applications where FRC use resulted in beneficial durability. The various properties addressed and the wide selection available in formulating matrix systems allow performancebased specification of concrete materials using fibers to become a viable reality. The objective of this report is to provide a historical basis about current knowledge for concrete professionals to use in tailoring new@ sustainable@ and durable concrete mixtures.
