Product brief:
Polyacrylonitrile fiber（PAN fiber）has high tensile strength, UV resistance. As the main reinforcement of cement concrete and asphalt concrete, 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. The real action and the use of PAN fiber in concrete has been accepted by the engineering community.

Physical property:

Application of the cement concrete：
1. Cement products, such as precast concrete panel and component

2. Cement concrete road, pavement, bridge deck, airfield runway

3. Port, sea terminal, bridge and cold region engineering

4. Highway anti impact retaining wall, anti impact damper

5. Pool, swimming pool, sewage treatment pond

6. Slab dam in hydraulic project and hydroelectric project

7. Basement wall, floor, roof, floor and other waterproof engineering

8. Shotcrete and pumping
 

Application of the asphalt concrete：
1. The overlay of old and newly built asphalt pavement

2. Pavement mending

3. The cold asphalt concrete pavement, cementation of fissures

4. Steel bridge deck pavement
 

Major function：Enhance the anti cracking ability

1. Good adhesive property, having supporting role for aggregate, to prevent the cracks

(1)Regulating water content, avoiding dry shrinkage cracks caused by excessive water evaporation.

(2)Adjust the temperature of concrete inside and outside because of Hydration Heat Evolved Rate, it reduces the crack depth, effectively prevents the occurrence and development of cracks.
 

2. 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, and the concrete frost resistance and impermeability.

（1）Reducing the brittleness of concrete, so that the concrete strength has been cracked.

（2）Improving the wear resistance, tensile strength and toughness of concrete.

（3）Impact resistance, earthquake resistance, anti cracking ability.

（4）Greatly improving the frost resistance of concrete, durability.
