Abstract

Abstract: In this paper，the fracture toughness of flexible fiber reinforced concrete is tested with the method of COD．and calculated at different ratio of flexible fiber Content．The results show that the flexible fracture toughness of fiber reinforced concrete is higher than the normal one.

Key words: fracture toughness, flexible fiber, cement concrete, three-point bending

摘要： 通过三点弯曲梁的试验，对柔性纤维砼的断裂韧性进行了测试和分析，并计算出不同柔性纤维含量的纤维砼的断裂韧性．表明柔性纤维砼的抗裂性能明显优于普通砼．
