The most common among the uses of red mud is using it as a building material. 1. Red mud is composed of a mixture of solid and metallic oxide-bearing impurities, and presents one of the aluminium industry's most important disposal problems. The red colour is caused by the oxidized iron present, which can make up to 60% of the mass of the red mud. The use of Red Mud not only increases the compressive and tensile strength of products made by this method, it also serves as a colourant.
