摘要: |
讨论了碳纤维(CF)和聚丙烯纤维(PF)、玻璃纤维(GF)和聚乙烯纤维(PeF)组成的混杂纤维增强混凝土的抗压强度、抗弯强度与纤维长径比之间的关系.试验结果表明,碳纤维、聚丙烯纤维、玻璃纤维和聚乙烯纤维的长径比对混凝土的抗压强度影响较小,而对抗弯强度则有明显影响. |

Relationship between the Mechanical Properties of Hybrid Fiber Reinforced Concrete and Length/Diameter Aspect Ratio of Hybrid Fiber |

Abstract: |
The relationship between compressive strength, flexural strength and length/diameter aspect ratio of fiber for the carbon and polypropylene hybrid fiber reinforced concrete(C-P HFRC), and for the glass and polyethylene hybrid fiber reinforced concrete(G-Pe HFRC) was tested and discussed. The testing results show that length/diameter aspect ratio of fiber obviously affects the flexural strength of C-P HFRC and G-Pe HFRC, though the compressive strength is slightly affected by the length/diameter aspect ratio. |
Key words: length/diameter aspect ratio,hybrid fiber,concrete,flexural strength |
