Description

Verfahren zur Herstellung von Bausteinen. Es ist bekannt, zur Herstellung von Bausteinen einen Mörtel aus Sand und Kalk zu pressen und an der Luft oder in einem Kessel unter Dampfdruck erhärten zu lassen. Gegenüber diesem bekannten Verfahren der Herstellung von Kalksandsteinen liegt das-Wesen der vorliegenden Erfindung darin, daß -- als Ausgangsgut an Stelle von Sand Tonmergel verwendet wird, der gebrannt und unter evtl. Beimischung von Kalk in üblicher Weise verarbeitet wird.Process for the production of building blocks. It is known to manufacture of building blocks to press a mortar of sand and lime and in the air or in to harden in a kettle under steam pressure. Compared to this known method In the manufacture of sand-lime bricks, the essence of the present invention lies in that - clay marl is used as the starting material instead of sand, which is burned and is processed in the usual way, possibly with the addition of lime.

Durch das Brennen des Tonmergels, der in der Hauptsache aus Kalk, Kieselsäure und Tonerde besteht, wird infolge der Anwesenheit des Kalkes die Kieselsäure aufgeschlossen und dadurch viel reaktionsfähiger als nach dem bekannten Verfahren. Sie quillt auf, so daß die Steine viel lockerer und leichter werden als Kalksandsteine und trotzdem dieselbe Druckfestigkeit aufweisen.By burning the clay marl, which is mainly made of lime, If there is silica and alumina, the presence of the lime turns the silica open-minded and therefore much more reactive than with the known method. It swells up so that the stones are much looser and lighter than sand-lime stones and still have the same compressive strength.

Es ist auch schon vorgeschlagen worden, Steine nach dem Kalksandsteinverfahren herzustellen, jedoch an Stelle von Sand gebrannten Ton zu verwenden. Trotzdem hier ein gebranntes Material zur Verwendung kommt, ist die Wirkung nicht dieselbe wie bei dem Verfahren nach vorliegender Erfindung, denn infolge Mangels einer genügenden Kalkmenge findet beim Brennen nur teilweise ein Aufschließen der Kieselsäure statt. Da Tonmergel außer Kalk noch Kieselsäure und Tonerde enthält, weisen die nach dem vorliegenden Verfahren hergestellten Steine außer den Eigenschaften der Kalksandsteine auch diejenigen der Backsteine auf.It has also been proposed to use the sand-lime brick method but using baked clay instead of sand. Still here a fired material is used, the effect is not the same as in the method according to the present invention, because due to the lack of a sufficient Lime amount only partially decomposes the silica during burning. Since clay marl contains silica and clay in addition to lime, they point to the bricks manufactured using the present process in addition to the properties of sand-lime bricks also those of the bricks on.

Ein weiterer Vorteil des vorliegenden Verfahrens besteht darin, daß es gestattet, ein häufig vorkommendes Ausgangsgut zu verwerten, das bisher nur auf Zement verarbeitet, nicht aber zur Bausteinherstellung benutzt wurde.Another advantage of the present method is that it allows a common source material to be used, which so far has only been based on Cement was processed but not used to manufacture building blocks.

Das Verfahren kann noch vereinfacht werden durch die Verwendung eines Tonmergels mit hohem Kalkgehalt, welcher dem durch das Brennen aufzuschließenden Kieselsäurean teil entspricht. In diesem Fall erübrigt sich eine besondere Beimischung von Kalk.The procedure can be further simplified by using a Clay marls with a high lime content, which corresponds to that which is to be broken down by firing Silicic acid part corresponds. In this case, a special admixture is not necessary of lime.

Besonders feste und haltbare Steine werden :erzielt, wenn man das Gut vor dem Pressen der Einwirkung von. gespanntem Dampf aussetzt. Dabei wird gleichzeitig der Vorteil erzielt, daß die alkalischen Bestandteile gebunden werden und kein späteres Ausblühen stattfindet.Particularly strong and durable stones are: Achieved if you do that Well before pressing the action of. exposed to tensioned steam. At the same time the advantage achieved that the alkaline components are bound and no later Blooming takes place.
