摘要：

Through the experiment on 90 concrete Specimens with the size of 100 mm X 100 mm X 100 mm and 45 concrete specimens of 100 mm X 100 mm X 400 mm,this paper Studied the influence of the grade of concrete strength, the Volume fraction of steel fiber and the freeze-thaw circulation times on the compressive strength splitting strength and rupture strength of steel fiber reinforced concrete(SFRC), the mechanism of peeling and damage of SFRC were analyzed. The results showed that when the grade of concrete strength is higher, the influence of steel fiber volume fraction on the resisting frost property was more obvious. The addition of steel fiber and the increase of the grade of concrete strength were the effective ways to improve the mechanical performance of SFRC under the action of freeze-thaw circulation.
