Description

Verfahren zur Herstellung von Formstücken aus Zement und Braunstein. Gegenstand der vorliegenden Erfindung bildet ein Verfahren zur Herstellung von Flächen für Wandbekleidung, Bodenbelag u. dgl., die sich durch große und gleichförmige Dichte, Widerstand gegen Verschleiß und Undurchdringlichkeit auszeichnen. Das Wesentliche bei der Herstellung derartiger Schichten ist die Verwendung von kicselige Gangart führendem Manganerz, insbesondere Braunstein.Process for the production of shaped pieces from cement and manganese dioxide. The present invention provides a method for producing surfaces for wall cladding, flooring, etc., which are characterized by large and uniform density, Distinguish resistance to wear and tear and impenetrability. The essentials in making such layers the use of kicselige gait is used leading manganese ore, especially brownstone.

Die Ausführung des Verfahrens geschieht zweckmäßig durch übereinanderlagerung mehrerer Schichten. Von diesen dient eine erste Schicht als Unterlage und besteht aus Mörtel von Zement, feinem Kies und Sand; eine zweite Schicht, gewissermaßen als Verbindungsschicht, besteht aus Zement und Braunstein in Körnern, und eine dritte Schicht besteht aus Zement und Braunstein in Pulverform. Letztere ist die der Abnutzung unterworfene und wasserdichte Schicht.The method is expediently carried out by superimposing one on top of the other multiple layers. A first layer of these serves as a base and exists from mortar of cement, fine gravel and sand; a second layer, so to speak as a connecting layer, consists of cement and brownstone in grains, and a third Layer consists of cement and manganese dioxide in powder form. The latter is that of wear and tear subjected and waterproof layer.

Praktische Versuche haben als eine gute volumetrische Zusammensetzung- des Gemenges für eine Wandstärke von 2o rnm folgende Verhältnisse ergeben: r. Schicht von r¢ mm Zusammensetzung: 113 Zement, 213 gewöhnlicher Kies; 2. Schicht von 3 mm Zusammensetzung: Zement, 1/3 Braunstein in Körnern und 1@3 gewaschener Sand; 3. Schicht von 3 mm Zusammensetzung: 1/2 Zement, % Braunstein in Pulver.Practical tests have shown a good volumetric composition- of the mixture for a wall thickness of 2o rnm results in the following ratios: r. layer of r ¢ mm composition: 113 cement, 213 ordinary gravel; 2nd layer of 3 mm Composition: cement, 1/3 brownstone in grains and 1 @ 3 washed sand; 3rd Layer of 3 mm Composition: 1/2 cement,% manganese dioxide in powder.

Das Verhältnis, in dem die verschiedenen Bestandteile gemischt werden sollen, hängt im übrigen von den Erfordernissen ab, die bezüglich. der Härte und der Undurchdringlichkeit gestellt werden. Die verschiedenen Bestandteile des Gemenges werden in kaltem Zustande gemischt, wobei so wenig wie möglich Wasser verwendet werden soll; und die Masse wird hierauf starkem Druck ausgesetzt' in allen Fällen, wo dies möglich ist. Arbeiten von großen Abmessungen können mittels Stößel, die von Hand oder Druckluft betätigt werden, komprimiert werden. Während des Abbindens wird das Gemenge während mehrerer Tage häufig abgespritzt und dann sehr luftig gelagert.The ratio in which the various ingredients are mixed should depend, moreover, on the requirements relating to. of hardness and impenetrable. The different components of the mix are mixed cold, using as little water as possible shall be; and the mass is then subjected to strong pressure 'in all cases, where possible. Working of large dimensions can be done by means of plungers that operated by hand or compressed air. During the setting the mixture is often sprayed off for several days and then stored very airy.

Die Verwendung von Braunstein gemeinsam mit Zement ist an sich bekannt. Man hat bereits vorgeschlagen, aus einer Mischung von Zement und Braunstein einen künstlichen Schiefer zu gießen. Es war aber nicht bekannt, daß auch in stärkeren Putz- oder Gußschichten das Material die oben angeführten Eigenschaften haben und durchaus volumenbeständig sein würde.The use of manganese dioxide together with cement is known per se. It has already been proposed to make one from a mixture of cement and brownstone pour artificial slate. But it was not known that even in stronger ones Plaster or cast layers the material have the properties listed above and would be quite stable in volume.
