摘要:

对国内某知名磷化工企业产生的磷石膏的成分、颗粒级配、渗透性、压缩性能和强度进行研究。结果表明,磷石膏中主要成分Ca SO4·nH2O约占92%,颗粒属于粉粒组,黏聚力低,属于低压缩性土范畴;级配不良,渗透系数为10-5~10-2cm/s;剪切角35°左右。

Abstract:

The composition,particle grading,permeability,compression property and strength of phosphogypsum produced by a well-known phosphorus chemical enterprise in China are studied.The results show that the main component of phosphogypsum is Ca SO4·n H2O,which accounts for about 92%.The particles belong to the silt group,the cohesiveness is low and it belongs to the category of low compressibility soil.The phosphogypsum is poor grading and the permeability coefficient is between 10-5-10-2cm/s.The shear angle is about 35°.
