A method for the integrated production of casts and mortars on the basis of hydraulic binders and in gravel substitute. In a first step, slag 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, and the iron-containing components and optionally plastics and paper are removed from the second fraction having a smaller average grain size. In a second step, the second fraction is subdivided into superfines and gravel, the superfines being used, after optionally removing non-iron metals, for producing hydraulic binders. In a third step, the hydraulic binders are used with superfines and tectosilicates for producing casts and mortars, and with gravel to produce a gravel substitute. |
