摘要
石墨烯具有优异的力学强度、阻隔性以及超大比表面积,通过对其进行物理或化学分散处理,能够制备高性能石墨烯水泥基复合材料。石墨烯通过调控水泥水化反应、改善孔隙结构以及界面结合等方式,可以改善水泥基材料的力学强度和耐久性能,在水泥基复合材料领域展现出巨大的应用潜力。本文综述了石墨烯水泥基复合材料的研究进展,总结了石墨烯在水泥基复合材料中的分散工艺和应用效果。同时,讨论了石墨烯的作用机理,并展望了石墨烯水泥基复合材料的发展趋势。
Graphene has excellent mechanical strength,barrier property and large specific surface area.As a result,it can be used to prepare the high-performance graphene cement-based composites by physical or chemical dispersion treatments.Graphene can improve the mechanical strength and durability of cement-based materials by regulating cement hydration reaction,improving pore structure and interfacial bonding,and show great application potential in the field of cement-based materials.The research progress of graphene cement-based composites was reviewed,the dispersion methods and the application effects of graphene were also summarized.At the same time,the mechanism of graphene was discussed and the development trend of graphene cement-based composites was prospected.
