Preparation method of concrete prepared from iron tailing micropowder activated by combined iron tailing functional material
The invention provides a preparation method of concrete prepared from iron tailing micro-powder activated by a combined iron tailing functional material. The concrete is prepared from the following materials: activated iron tailing micro-powder, iron tailing superfine sand, iron tailing fine sand, iron tailing medium sand, iron tailing coarse sand, cement, stone, water and a concrete water reducing agent; after iron is removed from the iron tailings, the iron tailings are screened and separated into iron tailings coarse sand, medium sand, fine sand and super-fine sand according to the particle size, and the iron tailings fine sand and the super-fine sand are taken to be mixed with a combined iron tailings functional material to be activated to obtain activated iron tailings micro powder; the activated iron tailing micro powder and the other raw materials are mixed and stirred evenly, then pouring is carried out, curing is carried out under the standard curing condition, and then demolding is carried out. The iron tailing micropowder activated by the combined iron tailing functional material is used for partially replacing materials such as cement and fly ash used in concrete production in a relatively high proportion, so that the utilization rate of the iron tailings is increased, the raw material cost is reduced, and the economic development is promoted while the environment is protected.
本发明提供了一种用组合铁尾矿功能性材料活化的铁尾矿微粉制作的混凝土的制备方法，制作材料包括：活化铁尾矿微粉、铁尾矿特细砂、铁尾矿细砂、铁尾矿中砂、铁尾矿粗砂、水泥、石料、水和混凝土减水剂；其中，将铁尾矿除铁后按粒径大小筛选分离为铁尾矿粗砂、中砂、细砂和特细砂，取铁尾矿细砂和特细砂与一种组合铁尾矿功能性材料混合活化后得到活化铁尾矿微粉；将活化铁尾矿微粉与上述其他原料混合搅拌均匀后浇注，在标准养护条件下养护后拆模。本发明采用一种组合铁尾矿功能性材料活化的铁尾矿微粉较高比例部分代替混凝土生产中使用的水泥和粉煤灰等材料，提高铁尾矿利用率的同时降低了原料成本，保护环境的同时也推动了经济发展。
