The effects of red mud on clay compounds

Recent study focused on the mixing properties of the clay and red mud compounds and the effects of red mud addition on clays with and without earth alkali carbonate content. Raw materials were added to compounds in natural form. Raw materials were applied as received in order to examine how mixing is possible in natural form without drying and grinding the red mud into powder. Highest amount of red mud content (50 wt%) was determined by mixing experiment. Compounds were prepared in pan mill and samples were extruded and analysed. Results indicated that red mud behaved in different way in carbonate and carbonate free clay but it is applicable for manufacturing of heavy clay products. It also revealed that the adequate mixing of red mud into the clay body is one of the most important question of the industrial application.
