The invention relates to additives capable of increasing slag activity and belongs to the technical field of additives. The additives are characterized by mainly comprising ethylenediamine tetraacetic acid disodium calcium, diethanol isopropanolamine, monoethanol diisopropanolamine and water. The additives have the advantages that the additives have a good complexing effect in an alkaline environment and can promote the dissolving of compact mineral components on the surface layer of slag, the dissolving speed of the mineral components of the slag is increased continuously under the continuous complexing effect of polyhydric alcohol amine, the hydration speed of the slag can be increased, and the activity of slag of various ages can be increased; the adding amount of the additives is 0.005-0.012% of the weight of the slag, and 7-day activity and 28-day activity can be increased by 11-15%.
