Industrial solid waste admixture for ultra-high performance concrete, and preparation method thereof
The invention discloses an industrial solid waste admixture for ultra-high performance concrete, and a preparation method thereof. The industrial solid waste admixture comprises, by weight, 300-400 parts of stainless steel slag, 100-200 parts of red mud, 30-40 parts of electrolytic manganese slag, 150-200 parts of high-iron low-calcium cement clinker, 2-5 parts of titanium gypsum and 1-3 parts of nano calcium carbonate. The industrial solid waste admixture has the characteristics of small particle size and low hydration heat, can be used for preparing ultra-high performance concrete with high strength, high volume stability and high durability, and can be applied to structures of bridges, buildings, ocean engineering and the like.
本发明公开了一种用于超高性能混凝土的工业固废掺合料及其制备方法，按重量份计，该工业固废掺合料包括300‑400份不锈钢渣，100‑200份赤泥，30‑40份电解锰渣，150‑200份高铁低钙水泥熟料，2‑5份钛石膏，1‑3份纳米碳酸钙。本发明的工业固废掺合料具有粒径小、水化热低的特点，可以制备强度高、体积稳定性高、耐久性高的超高性能混凝土，可应用于桥梁、建筑和海洋工程等结构。
