Iron tailing-based self-repairing concrete admixture and preparation method thereof
The invention provides an iron tailing-based self-repairing concrete admixture. The admixture is prepared from the following raw materials in parts by weight: 50-80 parts of iron tailing fine powder, 5-15 parts of an exciting agent, 10-20 parts of sulfate, 1-3 parts of a curing agent, 1-5 parts of a nano material and 0.5-1 part of a corrosion-resistant reinforcing agent. The iron tailing-based self-repairing concrete admixture disclosed by the invention not only consumes a large amount of tailing wastes and improves the ecological environment, but also greatly enhances the self-repairing performance of the concrete by using the admixture, thereby improving the durability of the concrete and prolonging the service life of the concrete.
本发明提供了一种铁尾矿基自修复混凝土掺合料，该掺合料由包括如下重量份数的原料制成：铁尾矿细粉50‑80份，激发剂5‑15份，硫酸盐10‑20份，养护剂1‑3份，纳米材料1‑5份，耐蚀增强剂0.5‑1份。本发明所述的铁尾矿基自修复混凝土掺合料不仅消纳大量尾矿废物，改善了生态环境，同时，该掺合料的使用，极大程度上增强了混凝土的自修复性能，进而提高了混凝土的耐久性，延长混凝土服役年限。
