摘要
运用TAW-2000型微机伺服多功能材料试验机,对不同强度混凝土掺入不同含量的钢纤维进行疲劳破坏试验研究。结果表明:在钢纤维体积含量一定范围内,随钢纤维体积含量增加,钢纤维混凝土的疲劳极限抗压强度增长十分明显;随钢纤维体积含量提高,混凝土的抗疲劳能力显著增强;随时间增长,应力曲线的上升段更加陡峭,下降段更缓慢,即钢纤维混凝土的疲劳强度、韧度均得到显著增长。
Tbe fatigue failure experimental study on the steel fiber with different content was carried out by using the TAW- 2000 Multi - function material experiments machine. The results showed that the tired extreme limit anti - presses strength increased linearly along with the content of steel - fiber. The ability of resist fatigue increased along with the content of steel - fiber. The rising segment of the curve is more steep and the downing slower along with the time. The strength and temper of steelfiber reinforced concrete be enhanced.
