磷尾矿、磷石膏和黄磷渣的地质聚合反应资源化利用研究进展

Research Progress on Resource Utilization of Phosphorus Tailings, Phosphogypsum and Yellow Phosphorous Slag by Geological Polymerization

  • 摘要: 随着磷矿开采量的增大,磷矿固废的库存量也逐年增加,对自然环境造成了严重的危害。概述了磷尾矿、磷石膏和黄磷渣固废资源的利用现状,以及碱激发地质聚合反应机理,对比了碱激发地质聚合物混凝土和普通硅酸盐水泥混凝土,阐述了通过碱激发地质聚合反应资源化综合利用磷尾矿、磷石膏和黄磷渣的现状。

     

    Abstract: With the increase of phosphate rock mining, the inventory of phosphate rock solid waste is also increasing year by year, which has caused serious harm to the natural environment. This paper summarizes the utilization status of phosphorus tailings, phosphogypsum and yellow phosphorus slag solid waste resources and the mechanism of alkali stimulated geological polymerization, compares alkali stimulated geological polymer concrete and ordinary portland cement concrete, and expounds the current situation of resource comprehensive utilization of phosphorus tailings, phosphogypsum and yellow phosphorus slag through alkali stimulated geological polymerization.
