Ultra-high-performance concrete suitable for western high-altitude areas and saline-alkali areas and preparation method of ultra-high-performance concrete
The invention belongs to the technical field of concrete, and discloses ultra-high-performance concrete suitable for western high-altitude areas and saline-alkali areas and a preparation method of the ultra-high-performance concrete. The concrete is prepared from the following raw material components in parts by weight: 30 to 50 parts of ordinary Portland cement, 5 to 20 parts of barium sulfate cement, 6 to 7 parts of steel fiber, 7 to 10 parts of silica fume, 20 to 27 parts of quartz sand, 1.5 to 2 parts of water reducing agent, 1.5 to 2 parts of sodium alginate, 7 to 10 parts of silica gel powder, 0.7 to 1 part of diethanol and 25 to 40 parts of nano emulsion. And 1-2 parts of lead powder can also be included. The concrete disclosed by the invention has the characteristics of ultrahigh strength, high fracture toughness, high freezing resistance, high chloride ion permeation resistance, high salt and alkali corrosion resistance, high radiation resistance and the like; and when the concrete is applied to concrete engineering buildings in western high-altitude areas, the anti-freezing capability, the radiation resistance and the saline-alkaline corrosion resistance of saline-alkaline areas can be greatly improved.
本发明属于混凝土技术领域，公开了一种适用于西部高海拔地区及盐碱地区的超高性能混凝土及其制备方法。该混凝土的原料包括以下按重量份数计的组分：普通硅酸盐水泥30‑50份、硫酸钡水泥5‑20份、钢纤维6‑7份、硅灰7‑10份、石英砂20‑27份、减水剂1.5‑2份、海藻酸钠1.5‑2份、硅胶粉7‑10份、二乙醇0.7‑1份、纳米乳液25‑40份。还可以包括铅粉1‑2份。本发明混凝土具有超高强度、高断裂韧性、高抗冻性、高抗氯离子渗透、高抗盐碱腐蚀性、高抗辐射性等特点；应用于西部高海拔地区混凝土工程建筑能大幅提高抗冻能力和抗辐射能力以及盐碱地区的抗盐碱腐蚀能力。
