纤维增强铁尾矿砂水泥基材料力学性能和孔隙结构实验OACSTPCD
Mechanical Properties and Pore Structure of Fiber Reinforced Iron Tailings Cement-based Materials
这是一篇陶瓷及复合材料领域的论文.本文详细研究和讨论了铁尾矿砂和PVA纤维对水泥基复合材料抗压强度、四点抗弯强度、弯曲韧性、孔隙结构.此外,建立了抗压强度与四点抗弯强度之间换算关系.结果表明:铁尾矿砂掺入对力学性能有增强效果,并且这种增强效果随着取代率的增加呈现先增加后减小趋势.而PVA纤维掺入后力学性能进一步提升,并且呈现出良好韧性.此外,铁尾矿砂取代率40％和PVA纤维复合时,基体内部孔隙明显降低.因此,认为当铁尾矿砂取代率为40％与PVA纤…查看全部>>
This is an article in the field of ceramics and composites.In this article,the effects of IOT and polyvinyl alcohol(PVA)fiber(PF)on the compressive strength,four-point flexural strength,flexural toughness,pore structure of cement-based composites were studied and discussed in detail.The conversion relationship between compressive strength and four-point flexural strength was established.The results showed that the incorporation of IOT had an enhanced effect …查看全部>>
