Polyacrylonitrile fiber（PAN fiber）is a new kind of synthetic reinforcement fiber for cement concrete and asphalt concrete. It is made of polyarylonitrile resins by special technique with high tensile strength and UV resistance. It can obviously improve the tensile strength, anti fatigue strength and bending strength of concrete. And also can improve the early cracking resistance of concrete. When used in the asphalt, it can significantly improve the asphalt adhesion, high temperature stability, fatigue durability, and has low temperature anti cracking and to prevent reflection crack, effectively improve the tensile, anti alkali, compressive and impact strength.

Functions
- Enhance the anti cracking ability

- Reducing the brittleness of concrete
- Improving the wear resistance, tensile strength and toughness of concrete.
- Improve impact resistance, earthquake resistance
- Regulating water content, avoiding dry shrinkage cracks caused by excessive water evaporation.
- To improve the impermeability and frost resistance of cement concrete, increase the durability of fiber, greatly       reducing the concrete pore size and the number of connected pores

Uses
1) Application of the cement concrete：
* Cement products, such as precast concrete panel and component
* Cement concrete road, pavement, bridge deck, airfield runway
* Slab dam in hydraulic project and hydroelectric project
* Basement wall, floor, roof, floor and other waterproof engineering
* Shotcrete and pumping
2) Application of the asphalt concrete：
* Pavement mending
* The overlay of old and newly built asphalt pavement

* The cold asphalt concrete pavement, cementation of fissures
