Chopped Acrylic Fiber Concrete Polyacrylonitrile Fiber For Cement Board


Description
Firstly, in terms of the shrinkage of concrete, the addition of polyacrylonitrile fiber can significantly reduce the shrinkage of
concrete. The distribution of polyacrylonitrile fiber controls the plasticity of cement concrete materials, undertakes the
shrinkage stress and toughness of local concrete, and effectively controls the diffusion of fine cracks in concrete.

Secondly, after mixing concrete and polyacrylonitrile fiber, a three-dimensional random support system is formed, which reduces
the shrinkage force of concrete and the cracking of concrete caused by the plastic shrinkage of cement paste.

Finally, polyacrylonitrile fiber has high elastic modulus, which increases the plastic strength of concrete crack resistance.
Applications
Polyacrylamide fiber is widely used in concrete today. Some cracks will appear in the drying process of cement concrete, and the
concrete mixed with polyacrylonitrile fiber can effectively prevent the continuous diffusion of cracks caused by dry shrinkage and
plastic deformation.
