Method for the integrated production of casts and mortars and of gravel substitute

A method for the integrated production of casts and mortars (17) based on hydraulic binders (15) and also of gravel substitute (16), characterized in that in a first method step slag (1) is divided into a first and a second fraction with different mean particle sizes, wherein the first fraction having a greater mean particle size is comminuted and returned to the slag (1), and iron-containing components (11) and optionally plastics and paper (12) are removed from the second fraction having a smaller mean particle size, in a second method step the second fraction is subdivided into superfines (21) having the smallest mean particle size and gravel (22) having a greater mean particle size, wherein the superfines (21) are used, after optionally removing non-iron metals (13), to produce hydraulic binders (15), and in a third method step hydraulic binders (15) are used with the superfines (21), tectosilicates (18) and optionally aluminum-containing components (19) to produce casts and mortars (17) and hydraulic binders (15) are used with the gravel (22), after optionally removing non-iron metals (13), to produce gravel substitute (16).
