钢纤维的几何特性 The geometry of the steel fibers 纤维的几何特性包括纤维的集束情况、纤维长度、长度与直径的比值、横截面形状、表面状况等。 The geometry of the fibers includes the cluster condition of the fiber, the length of the fibers, the ratio of the length to the diameter, the shape of the cross section and the surface condition. 曾滨将三种不同形状的钢纤维对混凝土基体增强作用从大到小进行了排序：超梯形钢纤维、梯形钢纤维、直线形钢纤维。黄育、王必斌等探讨了端钩形、铣削、方直形和波纹形四种不同钢纤维对活性粉末混凝土性能的影响，通过对综合混凝土的性能分析，发现端钩形钢纤维比其它纤维更优越。朱海棠、高丹盈等通过研究几种类型的钢纤维对高强混凝土抗剪强度的影响,发现切断弓型钢纤维对抗剪强度的增强效果较好。 Ceng Bin will be three different shapes of steel fiber concrete matrix to strengthen from big to small sorts: super trapezoidal steel fiber, trapezoidal steel fiber, straight steel fiber. Yukon huang, Wang Bibin hook, discusses the end milling, square shape and corrugated shape four different steel fiber on the properties of reactive powder concrete influence, through analyzing the comprehensive performance of concrete, found the hooked steel fiber is more superior than other fibers. Zhu Haitang, jean surplus by studying several types of steel fiber on the shear strength of high-strength concrete, steel fibers found to cut off the bow against the shear strength of the enhancement effect is better.
