Copper tailing geopolymer with high gelation activity and preparation method thereof

The invention relates to a copper tailing geopolymer with high gelation activity and a preparation method thereof. The copper tailing geopolymer is composed of silicon-aluminum powder and an alkali-activated solution. According to the method, a depolymerization reaction of a glass phase in a copper tailing geopolymer is fully excited by adding a composite alkali material; metakaolin, active slag powder and depolymerized low-polymerization Si (OH) 4 are added and subjected to a condensation polymerization reaction to generate CS (A) H gel, and resource utilization of the copper tailings, mineral admixtures and alkaline residue solid waste is achieved. According to the invention, industrial solid wastes such as the copper tailings, the slag powder, the kaolin and the alkaline residues are used as main silicon-aluminum raw materials, so that secondary resource utilization of the industrial solid wastes is realized, waste is turned into wealth, and the problems of space resource waste and environmental pollution
