METHOD FOR INERTING ASH, ARTIFICIAL POZZOLAN OBTAINED BY SAID METHOD

摘要

The invention concerns a method for inerting ash derived from urban waste incineration which consists in successively treating (19) the ash with a water-soluble phosphate (20) in the presence of water, in conditions adjusted to crystallise the hydroxylapatite and/or the whitlockite and calcining (22) it. The invention also concerns an artificial pozzolan obtained by subjecting ash derived from urban waste incineration to said inerting method.
