Method for preparing cementing material by using copper slag and steel slag as raw materials

The invention discloses a method for preparing a cementing material by using copper slag and steel slag as raw materials, comprising the following steps: slag activation of copper slag and steel slagis carried out; the cementing material is prepared by using the activated copper slag and the activated steel slag obtained in the S1 as raw materials. The cementing material is mainly prepared from the following ingredients (by weight): 30%-70% of activated copper slag, 20%-50% of activated steel slag, and 10-20% of an alkaline activator. By the slag activation and valuable metal recovery coupling technology, high-grade iron ore concentrate is recovered, and activated slag for preparing the novel cementing material is also obtained. Comprehensive utilization of smelting waste is realized, theslag storage problem is thoroughly solved, and various performance indexes of the cementing material are good. 本发明公开了种以铜渣和钢渣为原料制备胶凝材料的方法，包括如下步骤：对铜渣和钢渣进行矿渣活化；以步骤S1中所得的活化铜渣和活化钢渣作为原料进行胶凝材料制备：所述胶凝材料按重量百分比计，主要由如下组分制备得到：活化铜渣为30％-70
