초록

Nanomaterials are being actively studied in the fields of cement and concrete. However, research on other nanomaterials is insufficient because much of the carbon-based nanomaterials are made up of carbon nanotubes. Therefore, in this study, carbon-based water-soluble graphene oxide was mixed into mortar according to the cement replacement rate to conduct a characteristic evaluation. As a result, as the substitution rate of graphene oxide increased, workability decreased, and there was no effect of enhancing compressive strength. In addition, it was confirmed that the compressive strength decreased due to a large amount of air bubbles when the mixture was mixed for the purpose of improving workability.
