摘要：
Graphene oxide (GO) has significant strengthening and toughening effects on cement-based composites as a nano-reinforcement filler, and research progress on these materials is presented. The effects of GO on the properties of cementitious composites are summarized, including the dispersion stability of GO in a cement environment, the hydration properties, workability, rheological properties, mechanical properties and durability. Reinforcement and toughening mechanisms are proposed. Prospective research trends are discussed based on the problems already encountered.
