The invention relates to the technical field of comprehensive utilization of red mud, gypsum and fly ash, in particular to a PRM concrete reinforcing agent. The PRM concrete reinforcing agent is prepared from red mud, gypsum, fly ash and mineral powder, wherein the weight percentages of the raw materials are as follows: 5%-30% of the red mud, 5%-30% of the gypsum, 10%-50% of the fly ash and 10%-50% of the mineral powder. The preparation method comprises the following steps: respectively filtering out particles with the diameter of 0.5 or more cm from the red mud, the gypsum, the fly ash and the mineral powder, drying, and sufficiently and uniformly mixing. The PRM concrete reinforcing agent has the advantages of high strength and low price, utilizes a large amount of solid wastes such as red mud produced by alumina enterprises, desulfurized gypsum produced by thermal power plants, white gypsum produced by titanium dioxide enterprises, red gypsum and the like, changes wastes into valuables through comprehensive utilization, and solves the problem of environment-friendly solid waste treatment in the industries.
本发明涉及赤泥、石膏、粉煤灰综合利用技术领域，具体地说，涉及一种PRM混凝土增强剂。采用赤泥、石膏、粉煤灰和矿粉制备而成；各种原料的重量百分比为：赤泥5％‑30％、石膏5％‑30％、粉煤灰10％‑50％、矿粉10％‑50％；其制备方法是：先将赤泥、石膏、粉煤灰和矿粉分别过滤掉直径0.5cm以上的颗粒，烘干后充分混合均匀。本发明的优点：强度高、价格低，而且利用了氧化铝企业产生的赤泥、火力发电厂产生的脱硫石膏、钛白粉企业产生的白石膏、红石膏等大量固体废物，通过综合利用变废为宝，解决了这些行业面临的环保固废处理难题。
