Abstract

Waste concrete fine powder that is residue after aggregates recycling of demolished concrete is disposed as a lowmaterial of value. AndWaste sulfuric acid is the waste discharged in large quantities by industrial activity.In thispaper,we developed the handling process of waste concrete fine powder using waste sulfuric acid. By usingthishandling process, plaster of Paris with highpuritywas separable from waste concrete fine powder. Then, waste sulfuric acid was able to carry out neutralization processing.
