The invention relates to a phosphogypsum comprehensive resource utilization formula and process. The formula comprises phosphogypsum, a solid waste material, aggregate, a cementing material, a coagulator and clear water, wherein the aggregate adopts other solid waste materials or natural sandstone materials, the cementing material adopts cement, the coagulator adopts a special coagulator PLD-NGJ-10 type, the clear water adopts river channel water, the phosphogypsum accounts for 50-70%, the solid waste material or the natural sandstone material accounts for 15-35%, the cement accounts for 7%, the special coagulator PLD-NGJ-10 accounts for 0.2%, and the river water accounts for 7.8%. According to the invention, phosphogypsum is used for replacing clay to produce a sintered brick, so that secondary pollution to the environment can be avoided, and resources are saved, and compared with a common baking-free brick, the brick at the roasted part of the ardealite has the characteristics of high strength, good freezing resistance and no secondary pollution.
本发明涉及一种磷石膏综合资源化利用配方及工艺，包括有磷石膏、固废材料、骨料、胶凝材料、凝固剂和清水，所述骨料采用其他固废材料或者是天然砂石料，所述胶凝材料采用水泥，所述凝固剂采用专用凝固剂PLD‑NGJ‑10型，所述清水采用河道水，所述磷石膏的占比为50％‑70％，所述固废材料或者天然砂石料占比为15％‑35％，所述水泥占比为7％，所述专用凝固剂PLD‑NGJ‑10型占比为0.2％，所述河道水占比为7.8％。有益效果：利用磷石膏替代粘土,生产烧结砖,不仅可避免其对环境的二次污染，同时节省了资源，磷石膏材质焙烧处的砖与普通免烧砖相比，具有强度高、抗冻性好、无二次污染的特点。
