Polyacrylonitrile fiber reinforced material as a secondary concrete, polyacrylonitrile fiber can significantly improve the toughness and impact resistance of concrete.
And effectively prevent the emergence and development of cracks. Improve concrete impermeability, frost resistance and durability.
Also as a reinforcing fiber asphalt concrete industrial products. It can not only improve the asphalt pavement greater adhesion, high temperature stability, fatigue durability.
And has a low temperature cracking performance and preventing reflective cracking. Effectively improve the tensile, shear, compression and impact strength.


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.
