▎ 摘　　要

NOVELTY - The concrete comprises graphene oxide, metal fiber, 1020-1035 pts. wt. cementitious materials and 1122-1139 pts. wt. sand, The cementing material includes 613-620 pts. wt. cement, 152.75-155.5 pts. wt. silica fume, 204-207 pts. wt. fly ash, and 50.25-52.5 pts. wt. slag powder. The content of the graphene oxide is 0.01-0.3% of the weight of the gel material. The volume of the metal fiber is 1.2-2.5% of the volume of the ultra-high performance concrete. The cementing material includes 615-618 pts. cement, 153.75-154.5 pts. silica fume, 205-206 pts. fly ash, and 51.25-51.5 pts. slag powder. The graphene oxide is a nano-graphene oxide sheet. The sheet thickness of the nano graphene oxide sheet is 0.5-2.5 nm, and the sheet diameter is 0.5-12 ~mm. USE - Ultra-high performance concrete used in house, road, bridge and other building structure. Can also be used in construction of super high-rise building, large-span bridge and special building structure or facility. ADVANTAGE - The ultra-high performance concrete has high anti-folding strength, high temperature resistance, low-temperature performance, and improved mechanical performance and weather resistance. The loss of the dynamic and elastic modulus of the freeze-thaw cycle is very little. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of ultra-high performance concrete.
