Abstract: Polyvinyl alcohol (PVA) fiber is considered as one of the most suitable polymeric fibers to be used as the reinforcement of engineered cementitious composites (ECC), though the unique microstructure characteristics of PVA fiber add challenge to the material design. In this paper, the micromechanics based design procedure for a PVA-ECC suitable for structural applications is described, and practical design considerations including requirements on interface bond, matrix toughness, and flaw system are outlined for achieving balanced composite performances. The properties of an exemplary PVA-ECC design are summarized, including tensile behavior and compressive strength development, bending response, Young’s modulus, autogenous and drying shrinkage, and freeze-thaw durability.
