Preparation method of environment-friendly phosphogypsum-based composite stabilized macadam
The invention discloses a preparation method of environment-friendly ardealite-based composite stabilized macadam, and the environment-friendly ardealite-based composite stabilized macadam comprises the following components in parts by mass: 85-87% of aggregate macadam, 13-15% of ardealite, 1-1.5% of cement, 2-5% of quick lime and 1-2% of slag powder. The ardealite with the water content of 14% is mixed with aggregate macadam, cement, quick lime and slag powder with different particle sizes, water is added, stirring is conducted, and the ardealite-based composite stable macadam is prepared. According to the preparation method of the environment-friendly phosphogypsum-based composite stabilized macadam, in the prepared phosphogypsum-based composite stabilized macadam, the lime reacts with phosphorus and fluorine in the phosphogypsum to generate a precipitate which is converted into an inert substance, and the fluorine content of the treated phosphogypsum product meets the requirement of harmless treatment.
本发明公开了一种环境友好型磷石膏基复合稳定碎石制备方法，一种环境友好型磷石膏基复合稳定碎石，按质量份数计，包括：集料碎石85～87％、磷石膏13～15％、水泥1～1.5％、生石灰2～5％、矿渣粉1～2％；将含水率为14％的磷石膏与不同粒径的集料碎石、水泥、生石灰、矿渣粉混合，加水搅拌，制备磷石膏基复合稳定碎石。本发明采用上述一种环境友好型磷石膏基复合稳定碎石制备方法，制备的磷石膏基复合稳定碎石中，石灰与磷石膏中的磷和氟进行反应，生成沉淀物使其转化为惰性物质，处理后的磷石膏产品含氟量符合无害化处理的要求。
