▎ 摘  要

NOVELTY - A graphene oxide ultra-high performance concrete comprises 1020.75-1038 parts cement material, 80-120 parts steel fiber, water, quartz sand, graphene oxide, and polycarboxylic acid high performance water reducer powder. The mass ratio of water to cement material is 0.18. The mass ratio of quartz sand to cement material is 1.1. The mass of polycarboxylic acid high-performance water-reducing powder is 0.3% of cement material. The cement material comprises 680.50-692 parts cement, 136.10-138.40 parts silica fume, 68.05-69.20 parts fly ash, 40.83-41.52 parts slag powder, 95.27-96.88 parts quartz powder. The graphene oxide is 0.01-0.03% cement quality. USE - Graphene oxide ultra-high performance concrete. ADVANTAGE - The graphene oxide ultra-high performance concrete is environmentally-friendly. The graphene oxide ultra-high performance concrete is mixed with small amount of graphene oxide with excellent dispersibility. The bending strength ratio and toughness of ultra-high performance concrete are improved, and quality problem of existing ultra-high performance concrete is solved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide ultra-high performance.
