| 摘 要： | 通过试验研究了C40普通混凝土(PC),体积率为0.8%的钢纤维混凝土(SFRC)以及掺量为1.2 kg/m3的聚丙烯纤维混凝土(PFRC)分别在0次、25次、50次、75次、100次冻融循环后的质量损失,抗拉、抗压强度,基振频率以及动弹性模量,结果表明纤维的加入能抑制冻融对混凝土的损伤作用,且聚丙烯纤维的抑制作用大于钢纤维。

| Abstract: | Through the experimental study on C40 ordinary concrete (PC),the volume rate of 0.8% of the steel fiber reinforced concrete (SFRC) and dosage of 1.2 kg/m3 of polypropylene fiber reinforced concrete (PFRC) respectively in 0, 25 times, 50 times, 75 times, 100 times after freezing and thawing cycle of mass loss, tensile, compressive strength, the vibration frequency and dynamic modulus of elasticity, the results show that fiber can restrain the inhibitory effect of freeze-thaw damage in concrete, and the effect of polypropylene fiber is superior to steel fiber. |
