A review of graphene oxide/cement composites: Performance, functionality, mechanisms, and prospects

Owing to their excellent mechanical performance and durability, graphene oxide/cement composites (GO/CCs) exhibit good potential for the development of long-life green concrete. In this study, hot topics and research trends related to GO/CCs are summarised based on bibliometric methods. The effects on the mechanical performance of GO/CCs, as well as its transport properties, self-sensing performance, and enhancing mechanisms, are reviewed. Previous studies have demonstrated that the uniform dispersion of GO can lead to significant enhancements in the compressive strength, flexural strength, and tensile strength of cement composites, and it can also improve the resistance of corrosive media and sensitive resistance-strain responses. Hence, GO/CCs is highly promising as a smart cement-based material with high performance, good structural compatibility, and long service life. Future studies should investigate the self-sensing and long-term service performance of GO/CCs under the coupling of multiple environmental factors. Experiments and molecular dynamics simulations should be combined to reveal the enhancement and self-sensing mechanisms of GO/CCs.
