Abstract:
The flexural fatigue properties of glass fiber, organic fiber, and hybrid fibers reinforced concrete were studied. The test results show that alkali-resistant glass fiber can improve fatigue behavior of concrete; glass fiber has better effect on improving the fatigue behavior than polypropylene fiber. When the glass fiber concentrations are 2.7 kg·m-3, the flexural fatigue strength of concrete with glass fiber is 24% larger than that of plain concrete; when glass fiber and organic fiber concentrations are respectively 2.7 kg·m-3 and 1.3 kg·m-3, the flexural fatigue strength of hybrid fiber reinforced concrete is 35.0% larger than that of plain concrete; ie, hybrid fiber will have advantages of all kinds of fibers, which has more effect to improve the fatigue behavior of concrete than alone used glass fiber or organic fiber to concrete.
