Method for synergistically preparing geopolymer cementing material by utilizing aluminum ash and silica fume
The invention discloses a method for preparing a geopolymer cementing material by utilizing aluminum ash and silica fume synergistically, relates to the field of geopolymer cementing materials, and is used for preparing a geopolymer by utilizing the aluminum ash and the silica fume. The invention aims to solve the problems of large stacking amount, environmental pollution and the like of two metallurgical wastes, namely aluminum ash and silica fume. The aluminum ash and the silica fume are used as basic raw materials, and the alkali activator solution and the water in different mass ratios are added to prepare the geopolymer, so that the problem of environmental pollution caused by the aluminum ash and the silica fume is solved, and a low-carbon and environment-friendly new material is produced. The specific preparation method comprises the following steps: 1, preparing an alkali activator into a solution; 2, mixing the aluminum ash and the silica fume in proportion, adding the mixture into water, and uniformly stirring; 3, slowly adding an alkali solution into the mixture in the step 2; and 4, uniformly stirring the mixture obtained in the step 3, pouring the mixture into a mold, and carrying out curing molding, so as to obtain the aluminum ash-silica fume-based geopolymer. The invention can obtain the preparation method of the aluminum ash-silica fume-based geopolymer.
