▎ 摘　　要

NOVELTY - Graphene/barium titanate composite powder-modified cement comprises graphene/barium titanate composite powder, expanded polystyrene and silicate cement. The graphene/barium titanate composite absorbs modified cement powder. The filling rate of foaming polystyrene is 40-70vol%. The particle diameter of the foaming polystyrene is 2-6mm. The volume content of graphene/barium titanate composite powder is 2-5% of grapheme and barium titanate in mass ratio of 2:1-1:2. USE - Graphene/barium titanate composite powder-modified cement. ADVANTAGE - The graphene/barium titanate composite powder-modified cement ensures enhanced absorbing performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene/barium titanate composite powder-modified cement, which involves mixing graphene/barium titanate composite powder, expanded polystyrene, silicate cement, concentrated sulfuric acid, sodium nitrate, potassium permanganate and deionized water.
