Ultra-high-performance concrete for cold regions as well as preparation method and application of ultra-high-performance concrete
The invention particularly discloses ultra-high performance concrete for cold regions, which is prepared from the following raw materials: 600 to 900 kg/m < 3 > of cement, 200 to 240 kg/m < 3 > of silica fume, 100 to 120 kg/m < 3 > of coal ash, 1000 to 1200 kg/m < 3 > of machine-made sand, 20 to 26 kg/m < 3 > of a water reducing agent, 1 to 5 kg/m < 3 > of a defoaming agent and 170 to 220 kg/m < 3 > of water. And reinforcing fibers; the volume mixing amount of the reinforcing fibers is 1.0-3.5%, and the reinforcing fibers are at least one of steel fibers, reinforced steel fibers, polypropylene fibers and reinforced polypropylene fibers. The invention further discloses a preparation method of the ultra-high performance concrete for the cold region. The invention further discloses application of the ultra-high performance concrete used in the cold region as sprayed concrete.
本发明涉及，具体公开了一种寒冷地区用超高性能混凝土，其原料包括：水泥600‑900kg/m3、硅灰200‑240kg/m3、粉煤灰100‑120kg/m3、机制砂1000‑1200kg/m3、减水剂20‑26kg/m3、消泡剂1‑5kg/m3、水170‑220kg/m3；以及补强纤维；补强纤维体积掺量为1.0‑3.5％，补强纤维为钢纤维、增强钢纤维、聚丙烯纤维、增强聚丙烯纤维中至少一种。本发明还公开了上述寒冷地区用超高性能混凝土的制备方法。本发明还公开了上述寒冷地区用超高性能混凝土作为喷射混凝土的应用。
