摘要
通过试验研究了4种异形钢纤维对高强混凝土工作性能、物理力学性能和弯曲韧性的影响。探讨了不同异形钢纤维的增强、增韧机理,并指出钢纤维的掺入,使混凝土以主拉应力控制的劈拉强度等具有一定早强性。
An experimental study on effects of four deformed steel fiber on workabilities,mechanical properties and flexural thoughness of high strength concrete is reported. The reinforcing and toughening mechanisms of different deformed steel fibers are approached. At last,the paper indicates that addition of steel fiber make splitting tensile strength etc of concrete which is controlled by main tensile stress show high early strength properties.
