The invention relates to the technical field of geopolymer preparation, and concretely relates to a refining slag carbonation optimized geopolymer and a preparation method thereof. The refining slag carbonation optimized geopolymer is obtained by conducting a carbonation reaction on refining slag to obtain carbonized refining slag and then mixing and stirring an alkaline liquid excitant, the carbonized refining slag and fly ash. The refining slag is subjected to the carbonation reaction, so the problems of poor stability and poor stability of the industrial waste refining slag as a raw material for building materials, water conservancy projects, road engineering and the like due to high alkalinity and free CaO are effectively solved; the carbonized refining slag is used as a raw material for preparing the geopolymer with optimized refining slag carbonation, so reuse of industrial wastes is achieved; and the refining slag carbonation optimized geopolymer prepared in the invention has the advantages of favorabl
