High-dosage phosphogypsum stabilizing material of skeleton system and application thereof in road base
The invention provides a high-dosage phosphogypsum stabilizing material of a skeleton system. The material comprises phosphogypsum, broken stone, slag and a modifier; wherein the modifier consists ofa fiber reinforcing component, a harmful substance passivating component and a mixture fluidity improving component; the fiber reinforcing component is composed of one or more of polypropylene fibers,polyacrylonitrile fibers and polyamide fibers, and the harmful substance passivating component is composed of one or more of carbide slag powder, petroleum coke desulfurized ash and quicklime powder.The mixture fluidity improving component is composed of one or more of talcum powder, casein and sulfonated melamine formaldehyde resin. The high-dosage phosphogypsum stable material of the skeletonsystem has the advantages of being good in performance, wide in application range, convenient to operate and simple in preparation process; raw materials are mainly waste, the cost is low, energy consumption is low, secondary pollution to the environment is avoided, and the comprehensive utilization rate of phosphogypsum is high.
本发明提供一种骨架体系的高掺量磷石膏稳定材料，该材料包括磷石膏、碎石、矿渣、改性剂。所述的改性剂由纤维增强组分、有害物质钝化组分和混合料流动性改善组分组成；其中纤维增强组分由聚丙烯纤维、聚丙烯腈纤维和聚酰胺纤维的一种或多种组成，有害物质钝化组分由电石渣粉、石油焦脱硫灰和生石灰粉的一种或多种组成，混合料流动性改善组分由滑石粉、干酪素和磺化三聚氰胺甲醛树脂的一种和多种组成。本发明的骨架体系的高掺量磷石膏稳定材料具有性能好、适用范围广、操作方便、制备工艺简单；原料主要为废弃物、成本小耗能低、对环境无二次污染，磷石膏的综合利用率高。
