摘  要：通过混合氧化石墨烯（GO）纳米片层分散液和发泡水泥制备了GO/发泡水泥基材料，研究了GO对发泡水泥材料孔结构、抗压强度及微观结构的影响，研究结果表明，GO/发泡水泥基材料具有比较细小的孔径和均匀的分布、较高的抗压强度和规整有序的微观形貌，其微观形貌的主要特点是由规整有序的针状晶体和多面体状晶体构成。GO对水泥水化产物及聚集方式有模板效应和组装作用，二者的共同作用促使水泥水化产物成为有序排列的针状晶体和多面体晶体及聚集成规整有序的微观结构，本研究所得结果对于制备高强度发泡水泥基复合材料有积极意义。

Abstract: Graphene oxides (GO)/foam cement materials was prepared by mixing the GO nanosheets dispersion solution with foam cement materials. The effect of GO on porosity, compressive strength and microstructure of foam cement materials were investigated. The results showed that GO/foam cement materials has small pore with uniform distribution, higher compressive strength, regular and ordered microstructure, which consisted of regular needle-like and polyhedron-like cement hydration crystals. The formation mechanisms of GO on cement has template and assemble effect for cement hydration crystals and agglomeration methods, and combination of the template and assemble effects make the cement hydration products form ordered needle-like crystals and regular polyhedron-like crystals as well as forming regular microstructure. The research result has positive significances to prepare foam cement materials with high strength.
