In this study, in order to solve the problems of resource utilization electrolytic manganese residue and destruction natural resources by over-exploitation raw materials traditional ceramics, (EMR), red mud (RM), waste soil (WS) were used prepare self-foaming expanded ceramsite (SEC), different firing temperatures four groups with mixing ratios these three considered. Water absorption, porosity, heavy metal ion leaching, compressive strength cylinder SEC evaluated. The chemical composition microscopic morphology investigated XRD SEM. mechanism behind reaction among EMR, RM, WS was discussed. results showed that both temperature ratio significantly influenced basic performance SEC. With lower than 1200 °C, sphere appearance could be maintained all groups; however, density, seemed unacceptable. When rose up 1220 only found group whose 2:2.5:0.5. Under condition, excellent observed, a porosity 46.7%, bulk density 0.61 g/cm3, 3 d 26.82 MPa. described: when is 1180 an obvious took place, followed liquid phase being produced gas released decomposition Fe2O3 RM gypsum EMR. viscosity rate generation achieved balance, encapsulated anorthite (CaAl2Si2O8) began grow slowly. As time passed, prepared. study are great significance field artificial lightweight aggregate industrial solid utilization.
