The low tensile strength and poor facture toughness of cement-based materials are serious shortcomings that not only impose constraints in structural designs, but also affect the long-term durability of structures.In this regard, the benefits of fiber reinforcement in improving the fracture toughness of cement and concrete are well known.A critical parameter, which has a major effect on the mechanical performance of fiber reinforced cementitious composite, is the interfacial property between the fibers and the cementitious matrix.
