摘　　要：分析了含钛尾矿的矿物组成,结合高硅贝利特硫铝酸盐水泥的特点,提出了应用提取氧化钛后的尾矿、低品位铝矾土、含钛石膏制备高硅贝利特硫铝酸盐水泥的全新观点,并对该种水泥的烧结温度,冷却制度,强度及凝结时间等进行了系统的分析和讨论,结果表明它的烧结温度低,凝结时间及强度介于硅酸盐水泥和快硬硫铝酸盐水泥之间,含氧化钛较高的原料对高硅贝利特硫铝酸盐水泥性能没有明显负面影响。The authors analyzed the mineralogical composition of titanium tailings, and proposed a new view that applies titanium tailings, low-grade alumina and titanium-containing plaster to produce high silicon B-lite sulfur aluminate cement according to the feature of the cement. Moreover, they investigated systematically agglomeration temperature, cooling conditions, strength and setting time of the cement. The results show that the agglomeration temperature is low but the strength and setting time are situated in between silicate cement and rapid-hardening sulphoaluminate cement. It is to say that the high- titanium materials have no harm to high silicon B-lite sulfur aluminate cement.
