▎ 摘　　要

NOVELTY - Preparation of graphene-modified silica fumes, involves preparing modified graphene by reacting carboxy graphene and KH-550 (RTM: 3-aminopropyltriethoxysilane), and hydroxylating silica fumes using the modified graphene. USE - Preparation of graphene-modified silica fumes for use in cement and concrete materials. ADVANTAGE - The method provides graphene-modified silica fumes which increase strength of cement material, has excellent dispersibility and electrical property, and provides concrete with high fluidity, and excellent bending strength and toughness.
