摘　　要：通过对水泥凝结时间等物理性能的实验研究,确定用磷石膏代替天然石膏作水泥缓凝剂在普通硅酸盐水泥中应用的可行性。结果表明,磷石膏掺入普通硅酸盐水泥中后,能有效调节水泥的凝结时间,具有良好的缓凝效果,同时水泥各项物理性能指标均能达到水泥国家标准要求。An experiment was carried out by using phosphorus gypsum rather than natural gypsum as ce-ment retarder in portland cement to test its physical properties such as the setting time and decide its fea-sibility in cement production. The result shows that phosphorus gypsum works effectively in adjusting the setting time and retarding the setting process. Besides, its indexes of physical property meet the require-ments of the national standard.
