Iron tailing-based concrete admixture and preparation method thereof
The invention relates to an iron tailing-based concrete admixture and a preparation method thereof, and belongs to the field of building material preparation, the admixture comprises 60-70% of iron tailings, 5-10% of steel slag, 5-15% of blast furnace slag, 5-8% of fly ash, and 5-10% of desulfurized gypsum and fluorgypsum (mixed in a ratio of 1: 1). Solid wastes are adopted as the main raw material, the tailings are consumed, the production cost of the admixture is reduced, and meanwhile, the shortage of superfine mineral powder resources is relieved, so on the other hand, the use amount of cement can be reduced, and the energy and environment problems caused by cement production are reduced.
一种铁尾矿基混凝土掺合料及其制备方法，属于建筑材料制备领域，所述掺合料的原料组成包括铁尾矿60%‑70%、钢渣5%‑10%、高炉渣5%‑15%、粉煤灰5%‑8%、脱硫石膏和氟石膏（1:1混合）5%‑10%。本发明采用固废为主要原料，消耗尾矿，降低掺合料生产成本，同时缓解超细矿粉资源紧缺，另一方面可以减少水泥的使用量，降低因水泥生产所导致的能源和环境问题。
