石墨烯对水泥基材料耐久性的影响

Effect of Graphene on Durability of Cement-based Materials

为研究石墨烯(G)对水泥基材料耐久性的影响,通过掺配G水泥基材料并对试件进行Na2SO4、NaCl浸泡试验、扫描电镜(SEM)分析来研究G对于水泥基材料的耐久性影响。试验发现,水泥基材料在经过180d的硫酸盐溶液浸泡后,相较于不掺加G的试件,掺有0.045%G的水泥基材料试件的质量损失率最小。SEM分析表明,G的加入可以改善水泥基材料的内部结构,使其内部更加致密,从而提升其耐久性。

To study the effect of graphene (G) on the durability of cement-based materials,the effect of G on the durability of cement-based materials was studied by blending G cement-based materials and performing Na 2SO 4,NaCl soaking experiments and scanning electron microscopy (SEM) analysis on the specimens.It was found that the cement-based material after immersion in the 180 d sulphate solution had the lowest mass loss rate of the cement-based material doped with 0.045% G compared to the specimen without G.SEM analysis shows that the addition of G can improve the internal structure of cement-based materials,making the interior more dense,thus improving its durability.
