Preparation method of nano-modified concrete composite mineral admixture
The invention discloses a preparation method of a nano-modified concrete composite mineral admixture, which is prepared by mixing the following raw materials in parts by mass: 10-15 parts of ground copper tailing slag, 12-17 parts of blast furnace slag, 40-45 parts of fly ash, 30-35 parts of nano-modified mineral admixture and 0.4-1 part of active activator. The preparation method comprises the following steps: step a, selecting a certain amount of copper tailing slag, and drying the copper tailing slag through a dryer until the water content is less than 4%; and b, the copper tailing slag is ground through a grinding machine, and the dried copper tailing slag is ground for 5-15 min. The concrete composite mineral admixture has the advantages of being low in water content and high in density and enhancing the use strength of the concrete, the use strength of the concrete in the later period after the concrete composite mineral admixture is added can be guaranteed, the experience feeling of a user on the concrete composite mineral admixture is improved, and the requirements of the current market are met; the problems that the water content of the nano calcium carbonate slurry is high and the later strength of the concrete doped with the nano calcium carbonate is slowly increased are solved.
本发明公开了纳米改性混凝土复合矿物参合料的制备方法，以质量份计，由以下原料混合制成：磨细铜尾矿渣10‑15份、高炉渣12‑17份、粉煤灰40‑45份、纳米改性矿物掺合料30‑35份、活性激发剂0.4‑1份；制备方法包括以下步骤：步骤a：选取一定量的铜尾矿渣，通过烘干机将铜尾矿渣干燥至含水率小于4％；步骤b：通过研磨机对铜尾矿渣进行研磨，将干燥后的铜尾矿渣粉磨5‑15min。本发明实现了具备含水量低、密度高和增强混凝土使用强度的优点，能够保证加入混凝土复合矿物参合料后混凝土后期的使用强度，提高了使用者对混凝土复合矿物参合料的体验感，满足当今市场的需求，解决了纳米碳酸钙浆体含水率高和掺入纳米碳酸钙后混凝土后期强度增长缓慢的问题。
