Product Description:


Polyacrylonitrile Fiber Concrete Admixture for Enhancing Strength 

Polyacrylonitrile Fiber Concrete Admixture for Enhancing Strength

Description:

RQ®-Ⅵ fibers are very thin short fibers primarily made of Polyacrylonitrile (PAN) with

non-circular section shape by wet spinning for fiber reinforced high-performance concrete and

mortar. The fibers have excellent dispersion in the cement-based materials with a good bonding

property between fiber and matrix because of the surface treatment of hydrophilic modification.

RQ®-Ⅵ fibers can reduce and inhibit the plastic shrinkage and drying shrinkage of cement-based

materials. It can also improve the crack-resistance, impermeability, impact and fire resistance of

cement-based materials significantly.


Features:

1.Excellent dispersion. 

2. Unique shaped cross section. 

3. Excellent ageing resistance and adaptability. 

4.Effectively reduce micro-cracks and permeability. 

5. Impact and wear resistance increase.

6. Improve freeze-thaw resistance and fire-resistant.

 Usage and notes:


Dosage: Common dosage of 0.60~1.80kg/m3 (corresponding to the volume dosage of 0.05-0.15%).


 Length choice: 12-19mm fiber for concrete and 3-12mm for mortar.


 Mixing: Mixing time should be extended to ensure good fiber dispersion.


 Curing: The fiber reinforced concrete (or mortar) and common concrete (or mortar) with

the same construction and curing process.


 Design advice: Do not use the polyacrylonitrile fiber to replace structural strengthening

materials; Do not reduce the size of main structure;
