摘　　要：以化学试剂及工业原料配料,研究了磷石膏中P2O5含量对硫铝酸盐水泥熟料性能的影响。结果表明,随着P2O5含量的增高,硫铝酸盐水泥熟料的凝结时间延长,强度大幅下降。在使用磷石膏配制硫铝酸盐水泥熟料时,应考虑带入的P2O5对熟料矿物的影响,对配料公式进行调整。The effects of content of P2O5 in phosphogypsum on properties of sulphoaluminate cement clinker which was repared with industrial materials and chemical agents were studied. The results showed that the setting time of cement would be delayed and the strength of cement would be decreased drastically with the increasing of PO25. Therefore if the phosphogypsum should be used, the content of PO25 must be considered to adjust the raw meal proportioning scheme.
