Cement admixture, preparation method and application
The invention discloses a cement admixture, a preparation method and application. The cement admixture comprises the following raw materials: high-iron red mud, electrolytic manganese residues and water. The cement admixture is obtained by reacting the three raw materials in inert gas under high-pressure and high-temperature conditions. According to the preparation method of the cement admixture, the high-iron red mud and the electrolytic manganese residues can be treated at the same time, the two solid wastes are recycled to the maximum, environmental pollution is reduced, and the preparation process is simple, high in operability and suitable for large-scale production. According to the preparation method of the cement admixture, Fe2O3 in the high-iron red mud can be converted into Fe3O4, and resource recovery of iron ore in the high-iron red mud is achieved. The cement admixture disclosed by the invention is sufficient in preparation raw materials and low in cost, and the prepared admixture has relatively high gelling activity and can be used for partially replacing cement to prepare building materials.
一种水泥掺合料、制备方法及应用，所述水泥掺合料包括如下原料，高铁赤泥、电解锰渣、水，所述水泥掺合料由三种原料于惰性气体中，在高压、高温条件下反应而得。本发明水泥掺合料制备方法可同时处理高铁赤泥和电解锰渣，使两种固废得到资源利用最大化，减少环境污染，并且制备工艺简单，可操作性强，适合大规模生产。本发明水泥掺合料制备方法还能使高铁赤泥中Fe2O3转化为Fe3O4，实现高铁赤泥中铁矿的资源回收。本发明水泥掺合料的制备原料充足、成本低，制备出的掺合料具有较高的胶凝活性，可部分替代水泥用于制备建筑材料。
