der Mischung wird dieselbe in Formen einem Druck von 40 bis 80 atm. ausgesetzt, was sich ganz nach der Dichte der Formlinge richtet. Die so erzeugten Blöcke oder Steine werden in eine Trockenkammer eingesetzt, um zurückgebliebene Feuchtigkeit zu entfernen, worauf die Blöcke in einem geschlossenen Behälter, aus dem die atmosphärische Luft abgesaugt ist, der Einwirkung von Kohlen- säure ausgesetzt werden. Die Einleitung des Kohlensäuregases hat erst nach der Absaugung der Luft zu erfolgen.
Es ist hier anzuführen, dass, obgleich es bereits bekannt ist, die Blöcke in einem geschlossenen Gefässe unter Aufwendung eines allmählich zunehmenden Druckes mit Kohlensäure zu behandeln,

vorganges nach der Erfindung für den hier angestrebten Zweck, obgleich derselbe das gleiche Prinzip verfolgt, einfacher und schneller verläuft. Der auf die plastische Masse ausgeübte Druck ist verhältnismässig su klein, dass das Trocknen des Formlings in zwei Tagen vollendet ist, während bei der bekannten Herstellung künstlicher Lithographiesteine oder künstlichen Marmors bei Anwendung von etwa 260 atm. und mehr zum Trocknen der Formlinge drei bis vier Wochen nötig sind.
Das rasche Austreiben des Wassers wird sicher erzielt, wenn der Formling zu diesem Zwecke dem genannten geringen Drucke ausgesetzt wird, während bei dem Arbeitsvorgang nach früheren Verfahren das Austreiben der Feuchtigkeit nur durch ein sorgfältiges, allmähliches Verdunsten zu ermöglichen war, da bei Anwendung einer zu plötzlichen Hitze der Block rissig und wertlos werden würde. Das schnelle Trocknen des Bausteines erleichtert ebenfalls das Er-

Bei bekannten Verfahren würde ein Marmorblock oder ein Lithographiestein von 815 x 1050 75 MM etwa 3 bis 4 Wochen zu seiner Trocknung benötigen und sein Erhärten im Kohlensäure-Behälter würde sich ebenfalls nicht in einem geringeren Zeitraum und ausserdem nicht bei einem Druck von weniger als 24# atm. bewerkstelligen lassen.

the mixture is the same in molds at a pressure of 40 to 80 atm. exposed, which depends entirely on the density of the bricks. The blocks or stones produced in this way are placed in a drying chamber in order to remove any remaining moisture, whereupon the blocks are exposed to the action of carbonic acid in a closed container from which the atmospheric air is extracted. The carbon dioxide gas must only be introduced after the air has been extracted.
It should be noted here that although it is already known to carbonate the blocks in a closed vessel with the application of gradually increasing pressure,

process according to the invention for the purpose sought here, although the same follows the same principle, runs easier and faster. The pressure exerted on the plastic mass is relatively so small that the molding is completed in two days, while in the known production of artificial lithographic stones or artificial marble, about 260 atm. and it takes three to four weeks to dry the moldings.
The rapid expulsion of the water is certainly achieved if the molding is exposed to the low pressure mentioned for this purpose, while in the operation according to earlier methods, the expulsion of the moisture could only be made possible by careful, gradual evaporation, since when using one too suddenly Heat the block would become cracked and worthless. The fast drying of the building block also makes it easier to

With known methods, a marble block or a lithographic stone of 815 x 1050 75 MM would need about 3 to 4 weeks to dry and its hardening in the carbon dioxide container would also not take place in a shorter period of time and also not at a pressure of less than 24 # atm. get it done. A same one
