Graphene oxide (GO) has been found to have significant strengthening and toughening effects on cement-based composites, optimizing their properties. The effects of GO on these materials, along with potential future research directions, have been summarized in the study.
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.
