摘　　要：石墨烯(G)/氧化石墨烯(GO)以其优异的力学、导电以及导热性能在改善水泥基材料力学以及功能性等方面表现出良好的应用前景。然而,这些纳米材料在水泥基材料中难以分散,限制了它们在水泥基复合材料中的实际应用。近些年来,研究者们开始将纤维同这些纳米材料复掺到水泥基材料中,其分散性能得到了很大的提升。从材料在水泥基中分散问题、水泥水化过程、力学性能、功能性、耐久性能等5个方面系统地阐述了石墨烯及氧化石墨烯和其他纤维混杂对于水泥基复合材料的影响,对今后水泥基复合材料性能的提升具有指导作用。Graphene(G)/graphene oxide(GO)has shown promising applications in improving the mechanics and functionality of cement materials with its excellent mechanical,electrical,and thermal conductivity properties.However,these nanomaterials are difficult to disperse in cement-based materials,which limits their practical application in cement-based composites.In recent years,researchers have begun to mix fibers with these nanomaterials into cement-based materials,and its dispersion performance has been greatly improved.In this paper,the influence of graphene,GO and other fiber mixture on cement-based composite materials is systematically described from five aspects of material dispersion in cement,cement hydration process,mechanical properties,functionality and durability,which has a guiding role in improving the performance of cement-based composite materials in the future.
