聚丙烯纤维对高强混凝土抗压强度的影响研究

Effecting Study of Polypropylene Fiber on Compressive Strength of High-strength Concrete

研究了聚丙烯纤维掺量及长度对混凝土抗压强度的影响,结果表明,当聚丙烯纤维的长度为8mm时,所配制的混凝土强度最高。当聚丙烯纤维掺量小于0.5kg/m3时,高强混凝土抗压强度有所增加;而当聚丙烯纤维掺量高于0.5kg/m3时,高强混凝土抗压强度开始降低。

The influence of the amount and length of polypropylene fiber on the compressive strength of concrete was studied, the results showed that the strength of concrete is the highest when the length of polypropylene fiber is 8mm. When the polypropylene fiber content is less than 0.5kg/m3, the compressive strength of high-strength concrete increases, but when the polypropylene fiber content is higher than 0.Skg/m3, the compressive strength of high-strength concrete decreases.
