| 1。钢纤维表面粗糙了、截面呈不规则形。选用熔抽法消费就能抵达这个企图。表面缩短不平均而变得粗糙，同时截面也缩短成月牙形，添加与基体的伸缩缝钢纤维接触面积。 1. The surface of steel fiber is rough and the section is irregular. We can reach this goal by using the melting method. The surface shortens unevenly and becomes rough, at the same time, the section shortens to crescent shape, and the contact area of expansion joint steel fiber with the matrix is added. ⒉沿钢纤维轴线方向按必定间隔对纤维停止塑性加工。由于表面压成棱形，或压成波形，添加了机械粘结力。 2. Stop the plastic processing of the steel fiber at a certain interval along the axis of the steel fiber. Mechanical adhesion is added due to the surface being pressed into prisms or waveforms. ⒊使钢纤维的两头异形化。在两头制成弯钩。还有熔抽法抽取的大头形钢纤维。由于两头的伸缩缝钢纤维锚固作用，进步了抗拨力。 3. The two ends of steel fiber are deformed. Make hooks at both ends. There are also large head steel fibers extracted by melt drawing method. Due to the anchoring effect of steel fiber at both ends of expansion joint, the anti pulling force is improved. |
