Verfahren zur Herstellung von Bausteinen.
Die Erfindung bezieht sieh auf ein Verfahren zur Herstellung von Bausteinen aus Lehm, Sand und Zement. Das Neue besteht darin, dass der Lehm und Sand durch Vermahlen und Zerreiben zu einer griessartigen Masse innigst vermischt wird. Durch dieses Vermahlen und Zerreiben zu einer griessartigen Masse wird der Vorteil erreicht, dass der zu der Herstellung von Bausteinen zu verwendende Lehm in denselben griessartigen Zustande, wie der Sand gebracht und infolgedessen der der Lehmsandmischung zugesetzte Zement mit den griessartigen Lehm-und Sandteilchen innigst abbinden kann, so dass eine grosse Druckfestigkeit der Bausteine gewährleistet ist.
Die nach der vorliegenden Erfindung hergestellte griessartige Lehmsandmasse wird in bekannter Weise mit Zement versetzt, so dass durch den Zement die Abbindung der Masse vor sich geht, wobei der Zement als Härtemittel zur Erhöhung der Druckfestigkeit dient. Der Lehm kann, wie er in der Natur vorkommt, als trockener oder feuchter Lehm verwendet werden, nur muss der Feuchtigkeitsgehalt der Mischung beim Verarbeiten so geregelt werden, dass der Zement als Binde-und Härtemittel wirkt. Je trockener der Lehm ist, desto leichter und besser lässt sich eine griessartige Masse erzielen ; hiebei muss vor oder nach dem Zusatz von Zement eventuell etwas Wasser zugesetzt werden, um eine erdfeuchte Masse zu erreichen, die die Bindung durch Sand und Zement bewirkt.
Das Mischungsverhältnis kann je nach der Art der Grundstoffe verschieden gehalten werden. Aus der Mischung können Steine beliebiger Art hergestellt werden.
Das Verfahren kann beispielsweise mit folgendem Mischungsverhältnis zur Ausführung gelangen :
Es werden sechs Teile Lehm mit sechs Teilen Sand in einem Mischapparat mit Kollergängen zermahlen und zerrieben, um eine griessartige Mischmasse zu erzielen. Zu dieser innig vermischten griessartigen Masse wird dann ein Teil Zement zugesetzt und der Wassergehalt derart geregelt, dass eine erdfeuchte Masse vorhanden ist und die Abbindung vor sich gehen kann. Versuche haben ergeben, dass nach dem vorliegenden Verfahren und Mischungsverhältnisssen wasserunlösliche Bausteine mit einer Druck-

Process for the production of building blocks.
The invention relates to a method for the production of building blocks from clay, sand and cement. What is new is that the clay and sand are intimately mixed by grinding and rubbing into a semolina-like mass. This grinding and grinding into a semolina-like mass has the advantage that the clay to be used for the production of building blocks can be brought into the same semolina-like state as the sand and, as a result, the cement added to the clay-sand mixture can set very closely with the semolina-like clay and sand particles , so that a high compressive strength of the building blocks is guaranteed.
The gritty loam sand mass produced according to the present invention is mixed with cement in a known manner, so that the cement sets the mass, the cement serving as a hardening agent to increase the compressive strength. The clay, as it occurs in nature, can be used as dry or damp clay, only the moisture content of the mixture must be regulated during processing so that the cement acts as a binding and hardening agent. The drier the loam, the easier and better a semolina-like mass can be achieved; Here, before or after the addition of cement, a little water may have to be added in order to achieve an earth-moist mass that causes the bond with sand and cement.
The mixing ratio can be kept different depending on the type of base materials. Any kind of stones can be made from the mixture.
The process can be carried out, for example, with the following mixing ratio:
Six parts of clay are ground with six parts of sand in a mixer with pan grinders and grinded to achieve a semolina-like mixed mass. A part of cement is then added to this intimately mixed, semolina-like mass and the water content is regulated in such a way that an earth-moist mass is present and setting can take place. Tests have shown that according to the present process and mixing ratios, water-insoluble building blocks with a pressure
