<p>PURPOSE: A cement admixture composition using a pretreated slag, and a manufacturing method thereof are provided to recycle the pretreated slag generated from a molten pig-iron pretreatment process. CONSTITUTION: A manufacturing method of a cement admixture composition using a pretreated slag comprises the following: collecting and cooling the pretreated slag generated from a molten pig-iron pretreatment process(S11); pulverizing the cooled pretreated slag using a pulverizing unit, and classifying the pretreated slag using a slag treatment device(S12); fining the pretreated slag into the fineness over 3,800 square centimeters per gram using a micro powder generator(S13); and mixing the fined pretreated slag with 10~15wt% of electric furnace slag powder, and 100wt% of regular portland cement to make a cement admixture(S15).</p> |
