- Abstract:
- Polyvinyl alcohol (PVA) fiber is a new type of fiber with high tensile resistance, high elasticity, good hydrophilicity, especially good compatibility with Portland cement. In order to prepare high-toughness and large-deformation fiber-reinforced cementitious composites, the uniaxial tensile properties and flexural toughness of PVA fiber-reinforced cementitious composites were introduced, and the test results showed that PVA fibers had good crack resistance and toughening effects, which could significantly improve the crack resistance and deformation ability of cement-based composites. PVA fiber can significantly improve the flexural toughness of concrete, and the flexural toughness index of PVA fiber concrete is significantly higher than that of polypropylene (PP) fiber concrete.
