Method of reprocessing ash formed in the course of waste (refuse) incineration, particularly domestic waste incineration, for use in road construction

摘要

This is a method of reprocessing waste incineration ash in such a way that the waste incineration ash is suitable for use in road construction and in earthworks. For this purpose, the dominant, water-soluble calcium sulphate has to be bound in such a way that threshold values prescribed for water resources compatibility can be adhered to. This is achieved by the ash being stored with exclusion of air to prevent the formation of monocarbonate, resulting in complete binding of the calcium sulphate in ettringite.
