| 摘 要： | 研究了掺加异型塑钢纤维、钢纤维以及这两种纤维混杂的混凝土梁的抗弯冲击性能。测定了在不同纤维掺量下混凝土梁的初裂冲击次数、破坏冲击次数以及冲击能。试验结果表明:混掺纤维比单掺纤维显著提高了混凝土的冲击能和延性,但对初裂性能影响不大。

| Abstract: | The flexural impact behavior of concrete beams reinforced respectively with HPP, steel fiber and a combination of these two fibers are studied.The initial-crack,fracture impact cycle number and impact energy of these concrete beams with different fiber dosages are also tested.The results show that the impact energy and the toughness of the concrete with hybrid fibers are more enhanced than those with single kind of fiber but the initial-crack capability of the concrete has been affected a little. |
