钢纤维对混凝土疲劳性能增强的研究

Experimentation on Fatigue Behavior of Steel Fiber Reinforced Concrete

钢纤维混凝土是将少量的钢钎维均匀地撒布于混凝土板的上下表面 ,中间仍为素混凝土。利用了钢钎维的增强性能对板面薄弱部分进行加强。通过梁的弯曲疲劳试验 ,得到钢钎维混凝土和素混凝土的曲线 ;进行分析比较 ,得出钢纤维对混凝土疲劳性能增强机理。

Steel fiber reinforced concrete has a structure in which small quantity of steel fibers are evenly distributed on the surface and at the bottom of the pavement slabs while the middle body is still composed of plain concrete.In this way, the fragile parts are fortified.The evolvement of fatigue stain is obtained through the flexural fatigue behavior.and finally it is concluded that steel fiber can improve the fatigue behavior of the reinforced concrete.
