摘要
研究了不同纤维品种及纤维掺量高性能混凝土的抗压强度及抗裂性能。研究结果表明,掺加纤维对高性能混凝土的抗压强度影响不大,但可以明显增强高性能混凝土的早期抗裂性能,其中以单掺玄武岩纤维6kg/m3、复掺聚丙烯纤维0.5kg/m3和玄武岩纤维2.5kg/m3阻裂效果更为明显。
The compressive strength and early age crack resistance property of high performance concrete with different fiber kinds and different fiber dosages are researched. The experimental results show that the influences of different fibers on compressive strength of high performance concrete can be ignored, but it can dramatically improve the cracking resistance of high performance concrete at early age. And the cracking resistance effect is the most obvious with mono doping basalt fiber by 6kg/m3, and dual doping polypropylene fiber by 0.Skg/m3 and basalt fiber by 2.5kg/m3.
