An admixture for improving the activity of steel slag belongs to the technical field of admixtures.
The technical feature of the invention is that the additive is mainly composed of calcium disodium ethylenediaminetetraacetate, diethanol isopropanolamine, monoethanol diisopropanolamine and water.
The additive has a good complexing effect in an alkaline environment and can effectively promote the dissolution of dense mineral components in the surface layer of the steel slag. Again, the dissolution rate of the mineral components under the continuous complexation of the polyol amine in the steel slag. Continuous increase, which can increase the hydration rate of steel slag, improve the role of steel slag activity in all ages. The addition amount of the admixture is 0.005%-0.012% by weight of the steel slag, and the activity on the 7th day and the activity on the 28th day can be increased by 11%-15%.
