▎ 摘　　要

This work deals with the review of graphene-based cementitious composites, which is primarily focused on the effect on microstructure, hydration mechanism, and mechanical and durability properties. Nano-material-based cementitious composites are being developed to counteract concrete deficiencies in terms of strength and durability performance. Most frequent among those developments is the graphene-based nano-materials. Their application in the field of construction is more efficient than ordinary cementitious materials. Graphene is a 2D carbon material having a more specific surface area that promotes cement particles to interact during the process of the hydration, resulting in the increase in the hydration of cement and densifying the microstructure of cementitious composites. Recently, graphene-based nano-materials have drawn attention for application in construction due to their superior performance. The addition of a small quantity of graphene-based nano-material can significantly improve the microstructure and increase the mechanical strength of cementitious composites. The challenges and future possibilities of using graphene in cementitious composites are also specified in this review.
