The invention discloses a method for building a dam through red mud curing and dry heaping and a preparing device of mixed slurry for dam building through dry heaping, and belongs to the technical field of solid waste disposal in the aluminium oxide production process. According to the method for building the dam through red mud curing and dry heaping, red mud, power plant slag and a binding material are mixed and stirred evenly to form mixed slurry, the mixed slurry is dam building through curing and dry heaping and curing for storage capacity filling are achieved through the mixed slurry, according to the dry weight use proportion in the three components in the mixed slurry, the binding material: the power plant slag: red mud is 0.5-1:3-5:5-10, and the binding material comprises a stimulation component and the power plant slag. According to the technical scheme, the red mud and the slag can be comprehensively and effectively treated, dam building cost and slag transport cost can be saved, meanwhile, the ear
