Polyvinyl alcohol fiber for reinforcing concrete and cement is provided to offer high elasticity and high intensity of the fiber by dispersing polyvinyl alcohol monofiber, and to offer improved performance of the polyvinyl alcohol fiber. Polyvinyl alcohol fiber for reinforcing concrete and cement is manufactured with high tenacity polyvinyl alcohol filament. An aspect ratio of polyvinyl alcohol monofiber is 50~750. The aspect ratio is measured with the monofiber length(mm) and a section diameter. The polyvinyl alcohol filament includes 10g/d - 20g/d of intensity, 6% - 10% of elongation at break, and 20~100mum of the section diameter. The length of the monofiber is 5~15mm. |
