Development of the Bricks from Red Mud by Industrial Waste (Red Mud)

Abstract

Red mud emerges as the major waste material during production of alumina from bauxite by the Bayer's process. It comprises of oxides of iron, titanium, aluminum and silica along with some other minor constituents. In the present investigation experimental study was conducted for development of brick using red mud. Red mud brick of different trial mix were produced in the lab and test were conducted to find the properties of red mud brick properties found from tests were compared with the properties of ordinary bricks. It is found from the study that a red mud brick shows better performance than ordinary brick. As red mud bricks are eco-friendly & economical they protect the environmental also. Compressive strength of red mud bricks are more as compound to ordinary bricks. Water absorption is also more but within limit, change is size and weight losses of red mud brick are negligible in case of red mud bricks.
