Preparation method of composite tailing slag active micro-powder for concrete admixture
The invention discloses a preparation method of composite tailing slag active micro-powder for concrete admixture. The method comprises the following steps: mixing electrolytic manganese filter pressing slag, manganese flotation tailing slag and lead and zinc flotation tailing slag as main raw materials, adding an additive, roasting, cooling, drying, crushing, and milling to prepare the composite tailing slag active micro-powder for concrete admixture. The method allows tailing slag to be recycled, and the active micro-powder produced through the method can effectively improve the gelling activity of concrete, realizes recycling of the tailing slag, and has considerable economy and environmental protection significance.
