Industrial solid waste phosphogypsum composite stable road base material and preparation method thereof
The invention relates to an industrial solid waste ardealite composite stable road base material and a preparation method thereof. The ardealite composite stable road base material comprises the following components: 10-15% of gravel, 65-70% of ardealite, 6-10% of a composite curing agent and 10-15% of water. The composite curing agent is prepared from an exciting agent, a gelatinizing agent, a polymerization inhibitor, a water repellent agent, a surfactant and an early strength agent according to the mass ratio of (3 to 5) to (8 to 10) to (0.08 to 0.15) to (0.5 to 0.75) to (0.65 to 0.95) to (0.6 to 0.9) to (1 to 3). Soluble lead, arsenic and other toxic substances and heavy metals in the phosphogypsum are precipitated through the coagulant, and then the activity of the gelling agent is excited through the activator and the surfactant, so that the gelling agent wraps other harmful substances in the phosphogypsum. The method solves the problem of pollution caused by phosphogypsum, reduces the use of stones, and has the advantages of good social benefit, wide application prospect and the like.
本发明涉及一种工业固废磷石膏复合稳定公路基层材料及其制备方法，磷石膏复合稳定公路基层材料组分如下：碎石10～15％、磷石膏65～70％、复合固化剂6～10％和水10～15％。复合固化剂包括激发剂、胶凝剂、阻聚剂、疏水剂、表面活性剂、早强剂，七者的质量比为3～5：8～10：0.08～0.15：0.5～0.75：0.65～0.95：0.6～0.9：1～3。本发明通过混凝剂将磷石膏中可溶性铅、砷等有毒物质及重金属进行沉淀，再通过激发剂和表面活性剂激发胶凝剂活性，使其包裹住磷石膏中其他有害物质。本发明解决磷石膏所带来的污染问题，同时也减少对石料的使用，具有社会效益好、应用前景广等优势。
