▎ 摘　　要

Owing to their remarkable properties, graphene-based nanosheets (GNS) can enable the fabrication of high-performance and sustainable cement composites. Here we review recent advances in GNS-reinforced cementitious composites, focused on the novel strategies (i.e., dispersion, hybridization, coating, and dry mixing approaches) to effectively incorporate GNS into cement/concrete mixes. Furthermore, the impacts of GNS-reinforcement on the mechanical, durability and functional performance of cementitious materials were analytically covered. Lastly, we highlighted the increasing understanding of the fundamentals of the distribution and interplay of GNS within the complex cement microstructure - towards scientific principles to confidently translate GNS to the construction industry.
