Abstract：
This paper analyzed the properties of fiber reinforced concrete by using three different fiber content. Studies have shown that the incorporation of polypropylene fiber in concrete can effectively improve the concrete toughness, and can effectively avoid concrete cataclastic failure; fiber intake of freezing and thawing after concrete toughness have different effects, polypropylene fiber intake is greater than 30 kg/m3 concrete toughness index of freezing and thawing small effect on; of polypropylene fiber concrete in before and after freeze-thaw were than ordinary concrete doped fiber has good impermeability, freezing and thawing of polypropylene fiber mixing amount is greater than 30 kg/m3
of fiber reinforced concrete anti permeability performance does not affect significantly.
