钢纤维与水泥砂浆
枯结强度为钢纤维与基体界面间单位面积的枯结力.由于钢纤维混凝土在破坏时钢纤维的破坏形态主要是被拔出而非拉断，因此提高钢纤维在混凝土中的粘结强度具有十分重要的意义。钢纤维的枯结强度包括两方面内容:(”两种不同材料间的粘粉力。c2)钢纤维与一I体表面的机械啮合力.提高钢纤维在棍凝土中的枯结强度也应从这两方面入手，即(”通过合理的表面处理使钢纤维表面粗糙化，如表面的磷化等;(2)通过压痕。将钢纤维做成异a]等方法增加钢纤维的凹凸.提高钢纤维与基体间的机械啮合力。
The bond strength is the bond strength per unit area between steel fiber and matrix. It is very important to improve the bond strength of steel fiber in concrete because the failure mode of steel fiber is pulled out rather than pulled out. The bonding strength of steel fibers includes two aspects: (1) mojugl.37ix.com.cnmojugt.37ix.com.cnmojuhfc.37ix.com.cnmojugsa.37ix.com.cn liuliangwl.37ix.com.cnpeidianjl.37ix.com.cnthe bonding force between two different materials. C2) the mechanical meshing force between steel fibers and the surface of I body. To improve the setting strength of steel fibers in stick-solidified soil, we should start from these two aspects: (1) roughening the surface of steel fibers by reasonable surface treatment, such as phosphating on the surface; (2) indentation. Increasing the concave and convex of the steel fibers and increasing the mechanical meshing force between the steel fibers and the matrix.
