The invention relates to a method for the integrated production of casts and mortars (17) on the basis of hydraulic binders (15) and to gravel substitute (16). According to the invention, in a first step, slag (1) is subdivided into a first and a second fraction having different average grain sizes. The first fraction having a larger average grain size is size-reduced and returned to the slag (1), and the iron-containing components (11) and optionally plastics and paper (12) are removed from the second fraction having a smaller average grain size. In a second step, the second fraction is subdivided into superfines (21) and gravel (22), the superfines (21) being used, after optionally removing non-iron metals (13), for producing hydraulic binders (15). In a third step, the hydraulic binders (15) are used with the superfines (21) and tectosilicates (18) for producing casts and mortars (17), and with gravel (22) to produce a gravel substitute (16). |
