KAISERLICHESIMPERIAL
Die Herstellung einer künstlichen Steinmasse aus gelöschtem Kalk, Sand und ungelöschtem Kalk in der Weise, dafs das Löschen des letzteren unter Erhärtung der Masse vor sich geht, ist bekannt (Kleber, Geschichte der Kalksandziegel und des Kalksand-Pisebaues bis auf die Gegenwart, Mainz 1898, S. 7).The production of an artificial stone mass from slaked lime, sand and unslaked Lime is known in such a way that the latter is extinguished with hardening of the mass (Kleber, Geschichte the sand-lime bricks and the sand-lime Pisebaues up to the present, Mainz 1898, p. 7).
Auch ist bereits vorgeschlagen worden, gebrannten Wiesenk'alk zu derartigen Zwecken zu verarbeiten; denn nach Schirp & Co., Prospect über Erzeugung von Mauersteinen, Mainz 1898, S. 8, werden zur Herstellung von Kunstkalksteinen auch hydraulische Kalke benutzt, zu welchen wiederum die gebrannten Wiesenkalkmergel gehören (Feichtinger, die chemische Technologie der Mörtelmaterialien, Braunschweig 1885, S. 95).It has also already been proposed to use burnt meadow lime for such purposes to process; because according to Schirp & Co., Prospect on the production of bricks, Mainz 1898, p. 8, hydraulic limes are also used for the production of artificial limestone, to which in turn the burnt meadow lime marl belong (Feichtinger, the chemical Technology of mortar materials, Braunschweig 1885, p. 95).
Erfinder hat nun gefunden, dafs die aus Wiesenkalk hergestellten Steine eine praktische Benutzung deshalb nicht erlangt haben, weil sie eine zu geringe Festigkeit besafsen.The inventor has now found that stones made from meadow lime are practical Have not achieved use because they have too little strength.
Dieser Uebelstand wird nach vorliegender Erfindung in vollkommener Weise dadurch behoben, dafs das zum Löschen des gebrannten Wiesenkalkes dienende Wasser mit etwa 2 bis 3 pCt. Salpeter versetzt wird.According to the present invention, this disadvantage is thereby completely eliminated remedied that the water used to extinguish the burnt meadow limestone with about 2 to 3 pct. Saltpeter is added.
Wenn auch beim Anmachen von Kalk mit salzhaltigem Wasser Schädlichkeiten hervorgerufen werden (Feichtinger a. a. O., S. 69 und 77 unten), so erhärten doch andererseits gebrannte Wiesenkalke beim Anmachen mit salpeterhaltigem Wasser besser als bei Verwendung von reinem Wasser.Even if it caused harmful effects when mixing lime with salty water (Feichtinger op. cit., pp. 69 and 77 below), on the other hand, they corroborate Burnt meadow limes are better when mixed with water containing nitric oxide than when used of pure water.
Auf diese Weise ist es gelungen, aus gebranntem Wiesenkalk und Sand künstliche Steine herzustellen, welche in Bezug auf Festigkeit allen praktischen Anforderungen genügen. In this way it has been possible to create artificial ones from burnt meadow lime and sand To produce stones that meet all practical requirements in terms of strength.
Das Herstellungsverfahren ist folgendes:The manufacturing process is as follows:
Gepulverter, gebrannter, ungelöschter Wiesenkalk wird mit trockenem Sand oder dergl. vermischt und mit salpeterhaltigem Löschwasser zu reinem Brei angerührt. Dieser wird sodann mit so viel weiterem ungelöschten Wiesenkalk versetzt, dafs letzterer im Verhältnifs zu dem mit dem salpeterhaltigen Wasser gelöschten Kalk im Ueberschufs vorhanden ist, wobei jedoch die Gesammtmasse noch einen formbaren Brei bilden mufs. Nunmehr wird die Masse in Formen gebracht und darin so lange belassen, bis sie erhärtet.Powdered, burnt, unslaked meadow lime is mixed with dry sand or the like and mixed with nitric extinguishing water to a pure pulp. This will then mixed with so much more unslaked meadow lime that the latter in proportion to the latter Lime slaked with the nitric water is in excess, whereby however, the total mass must still form a malleable paste. Now the Put the mass into molds and leave it in until it hardens.
Der so hergestellte Stein wird sodann wiederholt mit Wasser behandelt, wobei er an Festigkeit noch zunimmt.The stone produced in this way is then repeatedly treated with water, whereby it strengthens still increasing.
Die unter Salpeterzusatz hergestellten Steine erhärten schneller und kräftiger und sind widerstandsfähiger als diejenigen Fabrikate, bei welchen der gebrannte Wiesenkalk mit Wasser ohne Salpeterzusatz angemacht ist.The stones produced with the addition of saltpetre harden faster and stronger and are more resistant than those brands in which the burnt meadow lime is mixed with water is dressed without the addition of saltpetre.
