摘要:
玄武岩纤维能有效改善混凝土材料的性能,但其对混凝土性能的影响规律还存在一定分歧. 以抗压和抗折强度作为力学指标,以抗氯离子渗透性能和早期收缩应变作为耐久性指标,探究不同玄武岩纤维掺量和规格对混凝土强度与耐久性的影响规律,分析短切玄武岩纤维掺杂混凝土材料的各项性能. 研究结果表明,短切玄武岩纤维对混凝土抗压强度的提高不明显,但对抗折强度则随掺量的增加而提高显著;纤维的体积分数为0.12%时,混凝土抗折强度提高约25%;长度较长及长径比较大的玄武岩纤维对混凝土抗折强度有更好的提高效果.玄武岩纤维的掺入会使混凝土抗渗性能略有下降,但也能有效降低混凝土的收缩应变,掺加玄武岩纤维后,混凝土28 d收缩应变降低约15%.
Abstract:
Basalt fiber can effectively improve properties of concrete materials. However, there are some divergences for its effects on concrete properties. Therefore, in this paper, effects of various fiber contents and sizes on concrete strength and durability are investigated, and properties of chopped basalt fiber doped concrete materials are characterized. In the research, compressive strength and flexural strength are used as mechanical indexes, while resistance to chloride-ion penetration and early-age shrinkage are used as durability indexes. Results show that although the contribution of basalt fiber to compressive strength of concrete is not obvious, flexural strength of concrete increases significantly as fiber content increases. There is a 25% increase when fiber content reaches 0.12%. Longer length and higher length/diameter ratio would bring further strengthening. Basalt fiber causes a slight decrease in concrete’s impermeability, but it can effectively restrain the shrinkage strain. With basalt fiber, decrease of shrinkage strain of concrete in 28 d is about 15%.
