用于制造钢纤维混凝土,任何方法生产的钢纤维都能起到强化混凝土的作用。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,以及纤维在基体中的分布和取向(η)的影响。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。加入钢纤维的混凝土其抗压强度、拉伸强度、抗弯强度、冲击强度、韧性、冲击韧性等性能均得到较大提高。 Steel fiber reinforced concrete and steel fiber produced by any method can strengthen the concrete. The reinforcing effect of fiber depends mainly on the strength of the matrix (FM), the ratio of the length to diameter of the fiber (the ratio of the length of steel fiber to the diameter of L and the diameter of D, that is, I/d), the volume rate of the fiber (the percentage of the steel fiber in the steel fiber concrete), the bond strength between the fiber and the matrix, and the distribution and orientation of the fiber in the matrix (ETA). Influence。 When the steel fiber reinforced concrete is destroyed, most of the fiber is pulled out rather than broken. Therefore, the improvement of the bond strength between the fiber and the matrix is one of the main control factors to improve the fiber reinforcement effect. The compressive strength, tensile strength, flexural strength, impact strength, toughness and impact toughness of the steel fiber reinforced concrete are greatly improved.
