Application of PVA Fiber in Cement Materials

Keywords

PVA fiber, concrete, cement, ECC, polyvinyl alcohol fiber

Polyvinyl alcohol fiber (referred to as PVA fiber) is a synthetic fiber made of high-quality polyvinyl alcohol (PVA) with a high degree of polymerization and processed by specific advanced technology.

Because this fiber is resistant to the alkalinity of cement, and has good adhesion and affinity with cement, it can replace asbestos as a reinforcing material for cement products.

The addition of PVA fiber can improve the defects of poor toughness, high brittleness and low tensile and flexural strength of cement materials.

The addition of PVA fibers in the ECC material has excellent tensile properties and the ability to control crack propagation.

The PVA fiber re-cement-based material has good dispersion resistance, can improve the anti-stripping ability, and can improve the frost resistance.

Advantages

1. It has good mechanical properties, high strength, high modulus and low elongation.

2. Strong acid and alkali resistance and chemical resistance.

3. Lightfastness

4. Corrosion resistance

5. Fiber has good dispersibility

6. The fiber has good affinity with cement, plastic, etc., and has high bonding strength.

7. Non-toxic and harmless to human body and environment.
