Abstract: 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.

Key words: graphene, dispersion, cement, mechanical strength, durability, mechanism
