Description

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