The reduced blast furnace titanium slag, made in Panzhihua Steel and Iron Corporation, contains a lot of minerals with low melting temperature, such as C2AS, CS, CMS2-CTS, etc. It can be used as the raw materials fully or partly replacing clay to produce cement clinker. These minerals in the reduced slag are beneficial to accelerate the formation of clinker minerals by reducing the eutectic temperature. The sintering temperature of clinker is about 1350 deg C when the reduced titanium slag is added in the raw mixes. The cement strength may reach 525 level when as high as 20 % of reduced high furnace titanium slag is used replacing clay. After water quenching, the reduced high furnace titanium slag contains mainly glass with dioptre and has potential activity. It is concluded that the water quenching reduced high furnace titanium slag can be used as cement mineral addition. The ratio of strength of compressive strength of the sample with 30 % slag to that of pure Portland cement in 28 days must be considered as the main factor to decide.
