Kind Code:
A
Abstract:
To provide a method of suppressing elution of fluorine and/or heavy metals from a solidified body when solidifying waste such as city waste incineration ash or steel slag, and a stabilization agent used for performing the elution suppressing method.
A hydraulic substance selected from Portland blast furnace cement, granulated blast furnace slag powder, granulated annealing blast furnace slag powder, and Portland cement is added to waste containing fluorine and/or heavy metals as the solidification agent.
