▎ 摘  要

Graphene oxide has been pointed as a reinforcing material of cement composites. Besides being a material with good dispersion in water, it has a high modulus of elasticity, high tensile strength, high specific surface and high thermal and electrical conductivity. In order to deepen the knowledge about the use of graphene oxide in cement composites, this paper presents a wide bibliographic review on the effects of graphene oxide addition on Portland cement composites. The methodology used for the selection of academic articles was ProKnow-C, (Knowledge Development Process - Constructivist), a literary revision tool that allows the disclosure of the current stage of academic knowledge related to the study topic. By means of this method it was possible to select, from a crude sample of 1354 articles, the 47 most relevant articles that showed the changes in mechanical properties, rheological behavior and microstructure of cement composites with addition of graphene oxide, as well as dispersion techniques used. Thus, the main conclusions, current research gaps and study opportunities were summarized, constituting a reference base to guide future work involving graphene oxide.
