▎ 摘  要

NOVELTY - An aqueous dispersion comprises 1-5 %mass graphene or graphene oxide, 0.5-2 %mass sodium dodecylbenzenesulfonate, 0.5-2 %mass polyvinylpyrrolidone, 0-10 %mass polycarboxylic acid water reducing agent, and water. USE - Aqueous dispersion used for preparing graphene concrete (claimed). ADVANTAGE - The aqueous dispersion has reduced graphene sedimentation in aqueous media. The graphene concrete has uniform and stable dispersion of graphene in cement concrete, excellent quality and performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of aqueous dispersion; and (2) preparation of graphene concrete.
