▎ 摘  要

NOVELTY - Modified graphene oxide cement concrete early strength agent, is claimed. USE - Used as modified graphene oxide cement concrete early strength agent. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing modified graphene oxide comprising (i) preparing graphene oxide, and (ii) preparing modified graphene oxide: preparing oxidized graphene into graphene oxide dispersion liquid having a concentration of 0.2-5 mg/ml, placing in 60-80 degrees C water bath, stirring, adding modifier dropwise, fully reacting, sonicating the solution for 0.5-1 hrs; and (2) application method of modified graphene cement concrete early strength agent comprising modified graphene oxide pretreatment step, the pretreatment step is firstly diluting the modified graphene oxide according to the concrete mixing ratio, so that the quality of the solvent mixture and the quality of water components in concrete equal and ultrasonically dispersing the mixture for 0.5-1 hours
