摘　　要：介绍了钛石膏中的杂质组成与形态,以及用钛石膏作水泥缓凝剂时,杂质对水泥性能的影响。研究结果表明,钛石膏中杂质主要为Fe(OH)3、FeSO4和Al(OH)3。杂质对水泥性能影响不大,不经预处理作水泥缓凝剂,其性能与采用天然石膏的水泥相当。The chemical composition and form of impurities in titanium gypsum and their effects on properties of cement were introduced when used as set retarder for Portland cement. Experimental results show that the impurities are mainly Fe (OH)_3, FeSO_4 and Al(OH)_3, and they may do little effect to Portland cement. The properties of cement with titanium gypsum are similar to those of Portland cement with natural gypsum,
