METHOD FOR PRODUCING CaCO3 COATED HIGH FUNCTIONAL FINE PARTICLE FROM SLUDGE AS BY-PRODUCT OF WASTE CONCRETE RECYCLING PROCESS

摘要

The present invention relates to a method for eco-friendly treatment and recycling of sludge and wastewater generated in the process of pulverizing waste concrete and recycling the pulverized concrete as aggregate. A high functional admixture for use in cement, mortar, etc., can be manufactured by separating only fine particles from sludge composed of a cement component and a sand component and coating calcium carbonate on the surface of the fine particles using mineral carbonation technology.
