The Study of the Red Mud Foam Lightweight Insulation Materials

Abstract:

Red mud foam lightweight insulation material was prepared by using red mud, fly ash, coal gangue and so on as raw materials by the method of foaming and sintering process. Influences of sintering temperature on thermal insulation material properties were studied. The micro-structure of samples was characterized by scanning electron microscopy (SEM) and mechanism analysis was made. The results show that in this condition, the optimum sintering temperature is 1120°C. The flexural strength of the samples is 0.41MPa, the compressive strength is 1.15MPa and the density is 479kg/m³.
