Beschreibung
Zusammenfassung:	Slag material resulting from waste incineration is comminuted before being mechanically, physically and chemically characterised, once the required mechanical physical and chemical properties are ascertained the material is premoulded to produce a prehydrated slag which can then be coated with an hydraulic binder. L'invention concerne un procédé d'élaboration de granulats (17) de construction à partir de mâchefers (1).Selon l'invention, le procédé d'élaboration de granulats (17) comprend les étapes suivantes:- criblage (2) des mâchefers,- caractérisation (4, 7, 11) des mâchefers criblés (1)- prémouillage des mâchefers caractérisés (23), avec un liant hydraulique,- enrobage (14) des mâchefers préhydratés (25) avec un liant hydraulique.
