Effect of Red Mud Content on the Property of Sintered Brick

Abstract:

The sintered brick was prepared with combining red mud and sale, as well as the sintered activation materials that were some industrial wastes. The effects of red mud content on property of sintered red mud-shale brick would be researched in this paper. The results showed when the ratio of red mud : sale : the sintered activation materials was 50:35:15, the sintered brick could meet the requirements of grade-A according to GB5101-2003, and the compressive strength reach MU25. The XRD showed that the main ingredient had been transformed into stabilized gehlenite, wollastonite and nepheline, as well as more glass phase and remained quartz.
