Multi-element activated composite admixture containing high-silicon type iron tailings and preparation method of multi-element activated composite admixture
The invention relates to the technical field of building materials, in particular to a multi-element activated composite admixture containing high-silicon type iron tailings, which is prepared from the following raw materials in parts by mass: 30-50 parts of high-silicon type iron tailings, 15-20 parts of red mud, 20-35 parts of coal gangue, 10-15 parts of alkaline residues and 1-5 parts of alkaline excitant. According to the multi-element activation composite admixture containing the high-silicon type iron tailings, the selected raw materials are the high-silicon type iron tailings, the comprehensive utilization rate of the tailings can be increased by preparing the admixture through multi-element activation, multi-element activation comprises mechanical activation, thermal activation, chemical activation and mechanical and chemical activation, and the activation efficiency is greatly improved; the selected red mud, alkaline residues and coal gangue are all solid wastes, and the materials are used for preparing admixtures for resource reutilization; and the selected high-silicon iron tailings and coal gangue contain rich metal oxides, so that the durability of the admixture can be improved. The environmental pollution can be reduced, the production cost is reduced, the natural ecological environment is protected, and the sustainable development of mineral resource recycling economy is promoted.
本发明涉及建筑材料技术领域，一种含高硅型铁尾矿多元活化复合掺和料，按质量份计原料组成如下：高硅型铁尾矿30~50份、赤泥15~20份、煤矸石20~35份、碱渣10~15份，碱性激发剂1~5份。本发明提供的含高硅型铁尾矿多元活化复合掺和料所选原料为高硅型铁尾矿，通过多元活化制备掺和料可以提高尾矿的综合利用率，所述多元活化包括机械活化、热活化、化学活化、机械‑化学活化多种方式进行，大大的提高活化效率；选取的赤泥、碱渣、煤矸石均为固废，将以上材料用于制备掺和料为资源再利用；所选的高硅型铁尾矿、煤矸石内含有丰富的金属氧化物可以提高掺和料的耐久性。能够减少环境污染、降低生产成本，保护自然生态环境，并促进矿产资源循环经济可持续发展。
