Title: (DE) Verfahren zur Herstellung von Bauteilen, insbesondere von Bauplatten sowie von Gemischen
(EN) Building components, especially construction boards, and mixtures are produced using foamed granules and a thermally treated binder mixture of combustion residues, water-containing substances and calcium oxide
Abstract:
(DE)

Die Erfindung betrifft ein Verfahren nach 19719684.5 zur Herstellung von Bauteilen, insbesondere von Bauplatten, sowie von Gemischen, wobei Reststoffe aus fossil betriebenen Kraftwerken zum Einsatz kommen. DOLLAR A Der Erfindung liegt die Aufgabe zugrunde, leichte und stabile Bauteile und/oder Gemische herzustellen, die vielseitig für den Innen- und Außenausbau verwendbar sind und ausschließlich aus Reststoffen bestehen. DOLLAR A Dies wird dadurch erreicht, daß erfindungsgemäß als Bindemittel ein thermisch behandeltes Gemisch aus Verbrennungsrückständen, wasserhaltigen Substanzen und CaO zum Einsatz kommt, wobei dieses (als Zuschlagstoff) mit aus recycelten Altglas geschäumten Granulaten oder ähnlich porösen Materialien und Wasser vermischt, ggf. anschließend in Formen verpreßt und zur Aushärtung gebracht wird.


(EN)

Building component and mixture production, using foamed granules and a thermally treated binder mixture of combustion residues, water-containing materials and calcium oxide, are new. The process of DE 19719684.5, for producing building components and mixtures by mixing binder and foamed granules with water, is modified by using, as binder, a thermally treated mixture of combustion residues, water-containing substances and calcium oxide, this mixture being mixed with foamed recycled scrap glass granules or similar porous materials and water, optionally compacted in molds and allowed to set. Preferred Features: The combustion residues are filter ashes. The water-containing substances are liquids or solids containing water or water of crystallization or partially dewatered gypsum dihydrate. The porous materials are foamed polystyrene, expanded clay, cenospheres, bentonite or the like. The mixture comprises 20-95 (especially 50-80) wt.% foamed glass granules and 80-5 (especially 50-20) wt.% binder.
