聚丙烯纤维对混凝土力学性能的影响

Impact on concrete mechanical properties of polypropylene fiber

在混凝土中加入不同掺量的聚丙烯纤维,形成聚丙烯纤维混凝土,通过立方体抗压强度试验、弯曲韧性试验、早期收缩抗裂试验,并与素混凝土试验结果进行对比,来确定不同掺量的聚丙烯纤维对于混凝土各个力学性能的影响,从而确定最佳的聚丙烯纤维掺量。

Different content of compressive strength test and Polypropylene fibers in the concrete form of polypropylene fiber flexural toughness test and early contractioncrack test, compared test to determine the impact of different dosage of polypropylene fibers for mechanical properties order to determine the best dosage of polypropylene fibers. concrete , by cube with plain concrete of the concrete, in
