METHOD FOR MANUFACTURING MAGNESIA PHOSPHATE COMPOSITE USING FERRONICKEL SLAG POWDER AND MAGNESIA PHOSPHATE COMPOSITE MANUFACTURED BY SAME USING FERRONICKEL SLAG POWDER

摘要

The present invention relates to a method for manufacturing a magnesia phosphate composite using ferronickel slag powder and to a magnesia phosphate composite manufactured by same using ferronickel slag powder, wherein the method comprises: a step (step 1) of preparing a mixture by mixing ferronickel slag powder with an alkaline activator; a step (step 2) of first activating the mixture by using a jet mill; and a step (step 3) of second activating the first activated mixture by mixing same with a phosphate, a plasticizer, a defoamer and water, and can manufacture a high-strength magnesia phosphate composite even by using a small amount of phosphate, and recycle resources and prevent environmental pollution by using ferronickel slag powder and bottom ash powder which have been disposed of.
