| ⒈改善基体对钢纤维的粘结性能;即改善混凝土基体，如采用更高强度混凝土 _Improve the bonding performance of the matrix to steel fibers; that is, improve the concrete matrix, such as using higher strength concrete ⒉增加纤维的粘结长度;即增加长径比，公式中lf/df _Increasing the bond length of fibers, i.e. increasing the ratio of length to diameter, lf/df in the formula ⒊改善纤维的形状、增加纤维与基体间的摩阻和咬合力;即提高钢纤维影响系数α (5) Improving the shape of fibers, increasing the friction and biting force between fibers and matrix, i.e. tongdiaop.71ix.comshusongdair.37ix.com.cnguanzhuang.37ix.com.cn ceshi.37ix.com.cnshuichuli.37ix.com.cn feishui.37ix.com.cnincreasing the influence coefficient of steel fibers |
