1.have the same high tensile strength, elastic modulus with the steel bars, elastic modulus 2.length:4mm-12mm
Polyvinyl alcohol fiber (PVA fiber) main action
1.change the brittleness of concrete, increase its toughness,improve its recrack capacity
2. To improve the workability of concrete, reduce the phenomenon of bleeding of concrete
3. Improve the workability of concrete, reduce the formation of the bleeding channel, greatly improve the impermeability of concrete
4. To improve the frost resistance of concrete
5. Improve the impact resistance of concrete
6. Improve the ultimate tensile properties of concrete and abrasion resistance
7. Improve the concrete ability to resist chloride ion
