Mechanical and Durability Performance of Polyacrylonitrile Fiber Reinforced Concrete

In this paper, the impact toughness, autogenous shrinkage, chloride penetration resistance, permeability resistance and abrasion resistance performance of prepared concrete reinforced with Polyacrylonitrile fiber (PAN fiber) were researched. The PAN fiber volume concentration percentages of cement were 0, 0.5%, 1.0%, 1.5% and 2.0%, respectively. The results showed that with the addition of PAN fiber, the toughness and durability performance were improved. Compared to the reference sample, the impact energy was significantly improved. The absorbed energy prevent specimens from deterioration by ...
