▎ 摘　　要

NOVELTY - Ultra-high performance anti-abrasion concrete, comprises 290-330 kg/m3low-heat silicate cement, 8.5-12.5 kg/m3metakaolin, 25-35 kg/m3pumice powder, 738-765 kg/m3basalt sand, 1200-1350 kg/m3basalt aggregate, 1.2-3.6 kg/m3basalt chopped fiber, 0.12-0.32 kg/m3β-cyclodextrin, 0.05-0.15 kg/m3graphene oxide, 2.58-3.65 kg/m3water reducing agent, and water (remaining amount). USE - The concrete is useful in high cold and high-altitude areas (claimed). ADVANTAGE - The concrete has high strength, high compactness, strong durability, low crack resistance, strong impact resistance, and strong anti-scouring ability.
