▎ 摘  要

NOVELTY - A graphene oxide-modified silica fume comprises 1 pt. wt. graphene oxide, 3-8 pts. wt. coupling agent and 2-500 pts. wt. silica fume. USE - Graphene oxide-modified silica fume used in preparing graphene oxide concrete composite material (all claimed). ADVANTAGE - The graphene oxide-modified silica fume enables graphene oxide concrete composite material with excellent performance and functionality. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the graphene oxide-modified silica fume, which involves using solvent and alkali solution; (2) graphene oxide concrete composite material, which comprises 150-350 kg/m3 cement, 40-100 kg/m3 fly ash, 800-1300 kg/m3 coarse aggregate, 500-700 kg/m3 fine aggregate, 20-50 kg/m3 graphene oxide-modified silica fume, 0.5-8.0 kg/m3 water reducing agent and 105-175 kg/m3 water; and (3) preparation of the graphene oxide concrete composite material.
