【摘要】 比较了不同形状钢纤维对不同强度等级混凝土力学性能的影响,分析了钢纤维掺量与混凝土强度之间的关系.结果表明,随钢纤维掺量的提高,钢纤维增强混凝土的各项力学性能都有不同程度的提高;纤维类型不同,对混凝土的增强效果各异,其中弓形和哑铃形钢纤维的增强效果优于平直形和波浪形纤维,并以哑铃形钢纤维为最佳.更多还原

【Abstract】 Effect of different types of steel fibers on the mechanical properties of concrete were investigated. The results indicate that the mechanical properties of concrete are improved with the increase in the volume percentage of steel fiber. The strengthening effects of bowshape and dumbbellshape steel fibers are better than that of straightshape and waveshape steel fibers. The dumbbellshape fiber has the best effect on strengthening, toughening and crackcontrolling of concrete.更多还原
