Summary:The invention discloses a high-activity admixture prepared from high-aluminum slag powder and a preparation method of the high-activity admixture. The high-activity admixture is prepared from the following components in percentage by weight: 60-82% of slag powder, 10-30% of silicon-calcium slag, 5-10% of desulfurized gypsum and 2-8% of an active synergist. The technical problem that unutilized furnace bottom slag can only be discharged to a solid waste storage yard, and huge pollution is caused to the environment is solved. The activity of the slag powder is greatly improved through mechanical activation and chemical activation, a way is developed for improving the additional value of the slag powder, and the big problem that the slag is difficult to treat is solved; the solid waste material is used for exciting the slag powder, so that the purpose of treating waste with waste is achieved. In the concrete production process, the cement consumption can be further reduced, the production cost is reduced, and th
