| 怎样保护钢纤维混凝土不被破坏。钢纤维的增强效果主要取决于基体强度(fm)，纤维的长径比(钢纤维长度l与直径d的比值，即I/d)，纤维的体积率(钢纤维混凝土中钢纤维所占体积百分数)，纤维与基体间的粘结强度(τ)，以及纤维在基体中的分布和取向(η)的影响。 How to protect steel fiber reinforced concrete from damage? The reinforcing effect of steel fibers mainly depends on the matrix strength (fm), the ratio of length to diameter (i/d), the volume ratio of steel fibers (volume percentage of steel fibers in steel fibre reinforced concrete), the bond strength (_) between fibers and matrix, and the distribution and orientation (_) of fibers in matrix. 当钢纤维混凝土破坏时，大都是纤维被拔出而不是被拉断，因此改善纤维与基体间的粘结强度是改善纤维增强效果的主要控制因素之一。加入钢纤维可生产各种钢纤维混凝土，应用范围较为广泛，一些公路路面、机场道面都可使用，增强性能，首先看钢纤维的效果。 When steel fiber reinforced concrete is destroyed, most of the fibers are pulled out rather than broken. songjiaoyou.07858.net diandongm.89ix.comfangdaomenw.89ix.com fengmao.89ix.comjialouyi.89ix.comtiaojiefad.89ix.comTherefore, improving the bond strength between the fibers and the matrix is one of the main control factors to improve the effect of fiber reinforcement. Steel fiber can be used to produce various kinds of steel fiber concrete, which has a wide range of applications. Some road and airport pavement can be used to enhance performance. First of all, the effect of steel fiber is considered. |
