摘　　要：磷石膏是一种利用率极低的工业固体废物。本文在以磷石膏:水泥:矿渣:黄砂为6:1:2:1,水灰比为0.1制建筑砌块的基础上,探讨了多种添加剂对砌块性能的影响,并得出了其增强效果为TJ-2﹥TJ-1﹥TJ-3﹥TJ-4﹥TJ-5的结论,有助于磷石膏的开发利用。Phosphogypsum is a solid industry waste whose rate of being used is very low. This thesis is based on using phosphogypsum to manufacture brick in the condition of phosphogypsum： cement： slag： sand is 6：1：2：1, and the rate of water and ash is 0.1, discussing the effect of several additives to the performance of brick, and come to the conclusion that the enhancing effect is TJ-2 〉 TJ-1 〉 TJ-3 〉 TJ-4 〉 TJ-5, it is beneficial to the integrative use of phosphogypsum.
