Semi-hydrated phosphogypsum-based geopolymer cemented phosphate tailing filling material and method for mine filling by using same
The invention provides a semi-hydrated phosphogypsum-based geopolymer cemented phosphate tailing filling material which is prepared by stirring the following components in percentage by weight: 5%-19% of a cementing material, 60%-70% of aggregate, 0.1%-1% of an additive and 20%-30% of water, the mixed filling material with high early strength, good bleeding property, good flowability and good water resistance is prepared by taking the byproduct semi-hydrated phosphogypsum in the phosphorus chemical industry as the main raw material and mixing the main raw material with the auxiliary material as the cementing material and taking the phosphate tailings and the mine waste rock as the aggregate. The semi-hydrated phosphogypsum, the phosphate tailings and the barren rock are all industrial waste residues, the phosphogypsum, the phosphate tailings and the barren rock are turned into wealth, pollution and harm of the phosphogypsum and the phosphate tailings waste residues to the environment are effectively controlled, meanwhile, the cost is low, and compared with similar products in the market, the phosphogypsum and the phosphate tailings have the obvious price advantage and better market prospects.
本发明提供了一种半水磷石膏基地聚物胶结磷尾矿充填材料，由胶凝材料、骨料、外加剂和水搅拌得到，各组分占比为：胶凝材料5％～19％、骨料60％～70％、外加剂0.1％～1％、水20％～30％；本发明以磷化工行业副产半水磷石膏为主要原料混合辅料作为胶凝材料，以磷尾矿及矿山废石作为骨料，制备出具有早期强度高、泌水性好、流动性好、耐水性好的混合充填材料。本发明的半水磷石膏、磷尾矿和废石均为工业废渣，将磷石膏和磷尾矿、废石变废为宝，有效地治理了磷石膏和磷尾矿废渣对环境的污染和危害，同时成本低廉，与市场同类产品相比，具有明显价格优势，具有更好的市场前景。
