Beschreibung
Zusammenfassung:	The invention relates to a process for the production of amorphous material from non sorted wastes, as well as from slags and fly ashes. It comprises the steps of drying the wastes by heat treating them at 600-1200 DEG C, melting them at 1300-1600 DEG C, transforming the crystal structure of the melt into an amorphous glassy mass by fast cooling thereof in water, and recovering said amorphous material. Complementary correcting oxides are further added during the heat treating step and/or the melting step. The amorphous material obtained can be used for the preparation of various building materials.
