Cellulose Fibers for Concrete


Cellulose fibers are a new type of concrete fibers developed after chemical synthetic fiber. The fiber has characteristics such as hydrophilicity, high strength, and high modulus. It can increase the crack resistance, freeze-thaw resistance, and reduce the permeability of concrete.
