Red Mud Based Geopolymer and Its Forming Mechanism

摘要

In order to resolve the problem of hoarfrost in red mud, prepare a geopolymer with sintered red mud and calcined bauxite tailings and fly ash and lime and gypsum. In the geopolymer, sintered red mud is 30%, gypsum 10%, calcined bauxite tailings and fly ash and lime 20% respectively. The compress strength of the geopolymer is 15.438MPa, as strength as a brick. It is a useful construction material for building road and filling stope and so on.
