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. • Hot topics for graphene oxide/cement composites (GO/CCs) have been widely reviewed based on bibliometric analyses. • Transport properties of GO/CCs are comprehensively summarised. • Enhancing mechanisms of GO/CCs are discussed at micro-scale and nano-scale. • The challenges and future prospects of GO/CCs for high-performance self-sensing materials are proposed.
