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。

关键词: 磷石膏, 缓凝剂, 水泥物理性能

Abstract:

An experiment was carried out by using phosphorus gypsum rather than natural gypsum as cement retarder in portland cement to test its physical properties such as the setting time and decide its feasibility in cement production. The result shows that phosphorus gypsum works effectively in setting time and retarding the setting process. Besides,its indexes of physical property meet the requirments of the national standard.

Key words: phosphorus gypsum, retarder, the physical property of cement
