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.

Directions for use:
(1) Volume polyacrylonitrile fiber cement concrete
A, generally every cubic meter of concrete fiber content is 0.6-1.2kg
B, based on sand material, stone, cement consumption changes and engineering requirements for crack. Fiber content can be adjusted. Maximum dosage of 1.5kg / m
Recommendation: Different particle gradation of aggregate blending effect greatly. With interest rates so choose a good level as possible.
(2) Content of asphalt concrete
Recommended dosage: asphalt quality 3 ‰ to 5 ‰
