Preparation method of anhydrous phosphogypsum gel material with high water resistance
The invention provides a preparation method of an anhydrous phosphogypsum gel material with high water resistance. The preparation method comprises the following steps: 1, carrying out wet grinding on100-150 parts by weight of silicon-aluminum solid waste, 100-130 parts by weight of water and 2.5-3.5 parts by weight of water reducer in a ball mill to obtain a silicon-aluminum solid waste slurry;2, uniformly mixing 2-20 parts of the silicon-aluminum solid waste slurry obtained in the step 1, 70-100 parts of anhydrous phosphogypsum and 2-20 parts of alkaline solid waste to disperse materials uniformly, then adding water according to the water-ash weight ratio of 0.4-0.5, meanwhile, adding 0.1-0.3 part of water reducer, and stirring uniformly to obtain the anhydrous phosphogypsum cementingmaterial with high water resistance. The method is simple and easy to implement, capable of reducing production cost greatly, and high in raw material waste utilization rate, solves the problems of land occupation, environment pollution and resource waste caused by solid waste stockpiling while the performance of the anhydrous phosphogypsum is improved, achieves the best use of materials, and hashigh economic benefits and environmental benefits.
本发明提供一种高耐水性无水磷石膏胶凝材料的制备方法，包括如下步骤：步骤1：按重量份记，将100～150份硅铝质固废、100～130份水、2.5～3.5份减水剂在球磨机中湿磨得硅铝质固废浆料；步骤2：将步骤1中所得硅铝质固废浆料2～20份、无水磷石膏70～100份、碱性固废2～20份混合搅拌使物料均匀分散，然后按水灰重量比0.4‑0.5加水，同时加入减水剂0.1‑0.3份搅拌均匀，得到高耐水性的无水磷石膏胶凝材料。本发明简单易行、能大幅降低生产成本，原料利废率高，在改善无水磷石膏性能的同时，解决了固体废弃物堆存占地、污染环境和资源浪费问题，实现了物尽其用，具有较高的经济效益与环境效益。
