摘要/Abstract

摘要： 为分析混杂纤维对自密实混凝土(SCC)工作性能和力学性能的影响,对不同养护龄期(7和28 d)、不同钢纤维(SF)掺量(0%、0.4%、0.8%和1.2%,体积分数)和聚丙烯腈纤维(PAN)掺量(0%、0.04%、0.08%和0.12%,体积分数)的SCC进行坍落扩展度、J环坍落扩展度、V型漏斗通过时间、立方体抗压强度试验,并通过扫描电子显微镜(SEM)对SCC的微观形貌进行分析。结果表明:随着纤维掺量增加,SCC的流动性和间隙通过性降低,抗离析性提升;单掺SF对SCC 7 d抗压强度的提高作用较单掺PAN显著;复掺纤维较单掺纤维对早期SCC抗压强度的提高作用更明显,且复掺纤维还能有效提升SCC的韧性与延性。

Abstract: In order to analyze the effects of hybrid fibers on working performance and mechanical properties of self-compacting concrete (SCC), collapse expansion degree, J-ring collapse expansion degree, V-shaped funnel passing time and cube compressive strength of SCC with different steel fiber (SF) content (0%, 0.4%, 0.8% and 1.2%, volume fraction) and polyacrylonitrile fiber (PAN) content (0%, 0.04%, 0.08% and 0.12%, volume fraction) at different curing ages (7 and 28 d) were tested, and the microstructure of SCC was analyzed by scanning electron microscopy (SEM). The results show that with the increase of fiber content, fluidity and pore passing ability of SCC decrease, and the segregation resistance of SCC is improved. The improvement effect of SF on 7 d compressive strength of SCC is more significant than that of PAN. The mixed fiber has a more obvious effect on compressive strength of early SCC than single-doped fiber, and the mixed fiber can also effectively improve the toughness and ductility of SCC.

Key words: self-compacting concrete, steel fiber, polyacrylonitrile fiber, working performance, mechanical property, microstructure
