RESEARCH OF PRODUCING HIGH SILICON B-LITE SULFUR ALUMINATE CEMENT BY TITANIUM TAILINGS

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.
