Diese Aufgabe wird erfindungsgemäß durch einen Zuschlagsstoff für Baustoffe wie Beton, Mörtel, Putz, Estrich od. dgl. gelöst, der aus mittels eines hydraulischen Bindemittels wie Ze­ ment, Kalk, Gips, Steinkohlenflugasche od. dgl. sowie Gemischen hieraus agglomerierten Mi­ neralfaserabfällen aus künstlich hergestellten Mineralfasern besteht.According to the invention, this object is achieved by an additive for building materials such as concrete, Loosened mortar, plaster, screed or the like, which consists of a hydraulic binder such as Ze ment, lime, gypsum, hard coal fly ash or the like as well as mixtures thereof agglomerated Mi mineral fiber waste consists of artificially produced mineral fibers.

Mineralfaserhaltige Abfälle fallen in bekannt hohem Maße an. Diese werden üblicherweise aufwendig entsorgt bzw. auf Deponien abgelagert. Ab dem Jahre 2005 ist gemäß TASi (Tech­ nische Anleitung Siedlungsabfälle vom 14.05.1993) in Deutschland eine Ablagerung auf De­ ponien nicht mehr zulässig. Durch die Erfindung wird nunmehr eine Verwertungsmöglichkeit hierfür geschaffen. Der so beschaffene Zuschlagsstoff ist einfach und insbesondere unter Be­ rücksichtigung ersparter Entsorgungskosten preiswert herzustellen, erlaubt vielfältige Einstellungsmöglichkeiten beim fertigen Baustoff, ist insbesondere auch resourcenschonend und spart Deponieraum.Waste containing mineral fibers is known to a high degree. These are common elaborately disposed of or deposited in landfills. From 2005, according to TASi (Tech instructions for municipal waste from 14.05.1993) in Germany a deposit on De ponies no longer permitted. The invention now makes it possible to use it created for this. The aggregate obtained in this way is simple and in particular under Be Taking into account saved disposal costs inexpensively, allows a variety of setting options  in the finished building material, is particularly resource-saving and saves landfill space.
