In order to effectively reuse red mud and coal gangue, foam glass was successfully prepared by sintering. The foaming of foamglass is ensured by adding foaming agent, foam stabilizer and fluxing agent to the raw materials including red mud, coalgangue and waste glass. Furthermore, the defects in the foam glass are also reduced. The obtained powder was dried at 105ºC and characterized by XRF, DSC-TG analysis, etc. According to cellular structure, apparent density and water absorption,the optimal type and ratio of foaming agent, foaming stabilizer and fluxing agent were revealed. The results indicate that theoptimized formula of foaming agent, foaming stabilizer and fluxing agent is 3% MnO2-2% Na3PO4-2% borax. The foam glassprepared under optimized conditions exhibits uniform porous distribution and suitable pore size with an apparent density of0.575 g/cm3 and water absorption of 4.61%. The research in this work could establish the technical foundation of red mudbasedporous material for industrial production. KCI Citation Count: 0
