Description
Verfahren zur Herstellung von porösen, säure- und wasserbeständigen Massen und Gegenständen Zusatz zum Patent 658 536 Die Erfindung betrifft die Weiterentwicklung des Verfahrens nach dem Hauptpatent, bei welchem zur Herstellung von porösen Betonkörpern mit zusammenhängenden, durchlaufenden Poreneiner Mischung von Zement und Sand in dem üblichen Mischungsverhältnis 7,5 bis I5 % Wasser zugesetzt werden. Dieses Gemenge wird unter Verwendung eines Schaummittels zum Schäumen gebracht und alsdann verformt. Nach diesem Verfahren hergestellte Röhren eignen sich zur Bodenentwässerung. Aus Beton (Sand und Zement) hergestellte Dränageröhren werden aber in verhältnismäßig kurzer Zeit von den im Boden enthaltenen Säuren angegriffen. Dieser Nachteil wird nun gemäß der vorliegenden Erfindung dadurch beseitigt, daß zur Herstellung von porösen, säure- und wasserbeständigen Massen und Gegenständen eine Mischung von trockenem Sand, Kittmehl, Wasserglas und Schaummitteln benutzt wird, die mit weniger als I5% Wasser verrührt und in bekannter Weise verformt wird.Process for the production of porous, acid and water resistant Masses and objects Addition to patent 658 536 The invention relates to further development the method according to the main patent, in which for the production of porous concrete bodies with contiguous, continuous pores of a mixture of cement and sand in 7.5 to 15% water can be added to the usual mixing ratio. This mixture is made to foam using a foaming agent and then deformed. Pipes made according to this process are suitable for soil drainage. the end Concrete (sand and cement) made drainage pipes are in proportion attacked by the acids contained in the soil for a short time. This disadvantage will now eliminated according to the present invention in that for the production of porous, acid and water-resistant masses and objects a mixture of dry sand, putty, water glass and foaming agents are used with less is stirred as 15% water and shaped in a known manner.
Nach diesem Verfahren hergestellte Erzeugnisse besitzen die Fähigkeit, das Wasser durch die vorhandenen zusammenhängenden, durchlaufenden Poren in einem sehr kurzen Zeitraum durch die Röhrenwände hindurchzulassen, so daß eine schnellere und gründlichere Entwässerung als unter Verwendung der bisher bekannten Röhrenerzielt wird. Dabei werden die Röhren selbst durch die im Boden enthaltenen Säuren nicht zersetzt. Herstellungsverfahren Zur Herstellung unserer Massen und Gegenstände mit zusammenhängenden, durcblaufenden Poren dient eine Mischung z. B. von Bog lehmfreiem, vollständig trockenem Sand in einer Kornstärke bis zu 2mmn, 2og Kittmehl, insbesondere dem von der I. G. Farbenindustrie AG. in Frankfurt, Main hergestellten und in den Handel gebrachten Säurekitt Höchst S.W. 2o, 6 ccm Wasserglas und 8 ccm Wasser, in welchem ein Schaummittel, wie z. B. das von der I. G. Farbenindustrie hergestellte, im Handel befindliche Schaummittel >; Iporit«, im Verhältnis von 2 bis q.: i oo aufgelöst ist. Es können aber auch .andere säure-und wasserbeständige Bindemittel, wie z. B. kittartige Stoffe in Mischung mit Schamottemehl, verwendet werden.Products made according to this process have the ability to the water through the existing contiguous, continuous pores in one allow a very short period of time to pass through the tube walls, so that a faster and more thorough drainage than is achieved using the previously known tubes will. The tubes themselves are not damaged by the acids contained in the soil decomposed. Manufacturing process To manufacture our masses and objects using coherent, continuous pores a mixture z. B. from Bog clay-free, completely dry sand with a grain thickness of up to 2mmn, 2og cement flour, in particular that of I. G. Farbenindustrie AG. manufactured in Frankfurt, Main and in the Commercial acid putty Höchst S.W. 2o, 6 cc water glass and 8 cc water, in which a foaming agent, such as. B. that manufactured by I. G. Farbenindustrie, commercially available foam concentrates>; Iporit «, in the ratio from 2 to q .: i oo is dissolved. However, other acid- and water-resistant binders, such as B. putty-like substances mixed with fireclay flour can be used.
Diese Stoffe werden m einem Gefäß unter schlagartigem Rühren 'm eine gieß- und formbare schaumartige Masse verwandelt.These substances are mixed in a vessel with sudden stirring castable and mouldable foam-like mass transformed.
Zur Erzielung der zusammenhängenden, durchlaufenden Poren dient erfindungsgemäß das besondere Mengenverhältnis der an sich bekannten festen Stoffe zu der Feuchtigkeit, welche erfindungsbemäß weniger als etwa 15 % der gesamtenii Mlasse beträgt.According to the invention, the purpose is to achieve the contiguous, continuous pores the particular proportion of the per se known solids to the moisture which, according to the invention, is less than about 15% of the total ii Mlasse is.
