Die Herstellungsweise dieses Bausteines besteht in einem Verfahren, nach welchem die Steine eine vollständige Wetterbeständigkeit, Festigkeit und Dauerhaftigkeit erhalten.The production method of this module consists of a process according to which the Stones get complete weather resistance, strength and durability.
Man hat bis jetzt wohl versucht, eine Masse aas gewöhnlichem Gips und Kalk (Aetzkalk) unter Zuhilfenahme von Schwefelsäure oder schwefliger Säure in eine krystallisirte, feste Masse zu verwandeln, jedoch vergebens. Praktische Erfahrungen lehrten, dafs ein derartiges Verfahren nicht den gehegten Erwartungen entspricht,So far you have probably tried to create a mass aas common gypsum and lime (caustic lime) with the help of sulfuric acid or to transform sulphurous acid into a crystallized, solid mass, but in vain. Practical Experience has shown that such a process does not meet the cherished expectations is equivalent to,
1. weil durch Anwendung von Schwefelsäure die Bildung von schwefelsaurem Kalk aus Aetzkalk eine plötzliche ist und dadurch keine innige Verbindung von Gips und Kalk stattfindet,1. because the use of sulfuric acid results in the formation of sulphate of lime from caustic lime is a sudden one and therefore no intimate connection between gypsum and lime takes place,
2. weil durch Anwendung von schwefliger Säure die Krystallisirung des gewöhnlichen, ohnehin schon langsam bindenden Gipses so verlangsamt wird und derselbe so an seiner Bindekraft verliert, dafs eine gleichmäfsige und dauerhafte Festigkeit der Masse zu Steinzwecken niemals erzielt werden kann; denn die Erfahrung hat gelehrt, dafs, je länger der Gips sich in mit schwefliger Säure gemischtem Wasser befindet, ohne abzubinden, desto geringer seine Bindekraft und sein Erhärtungsgrad wird. Ferner ist es auch zur Genüge bekannt, dafs zu lange im Wasser befindlicher Gips versäuft, wie man im Volksausdruck zu sagen pflegt, überhaupt nicht mehr abbindet und seine Bindekraft vollständig verliert.2. because the use of sulphurous acid leads to the crystallization of the ordinary, already slowly binding plaster is so slowed down and the same so on his It loses its cohesiveness, so that a uniform and permanent strength of the mass for stone purposes is lost can never be achieved; for experience has shown that the longer the plaster of paris is in water mixed with sulphurous acid without setting, the less its cohesiveness and its degree of hardening. Furthermore, it is well known that it has been in the water for too long Plaster of paris drowns, as people say in the vernacular, no longer sets at all and completely loses its cohesiveness.
Diesen Uebelständen abzuhelfen, soll das neue Verfahren dienen.The new method is intended to remedy these evils.
Dieser Zweck wird dadurch erreicht, dafs man in einem Quantum Wasser pulverisirten Schwarzkalk ablöscht, ihn dann durch Zusatz von 66 gradiger Schwefelsäure theilweise in schwefelsauren Kalk verwandelt, um später eine innigere und raschere Verbindung mit dem Gips zu erzielen, dann das betreffende Füllmaterial, welches aus Sägemehl, 'Torfmull, Spreu, Asche, Sand u. s. w. (je nach Bedarf) bestehen kann, zugiebt und dasselbe mit dem Gemisch innig vermengt. Hierzu mischt man dann den zu diesem Zwecke sorgfältig gebrannten und, wenn nöthig, mit Boraxlösung präparirten Gips, welcher sofort mit der übrigen Masse eine innige Verbindung eingeht und in kurzer Zeit, mit der ganzen Masse in Formen gegossen, vollständig zu Stein erhärtet. Es wird noch bemerkt, dafs die Verwendung des bekannten, in dem Handel, befindlichen Baugipses bei der Fabrikation vollständig ausgeschlossen ist, da derselbe mit der vorgenannten Masse keine Verbindung eingeht, viel weniger erhärtet.This end is achieved by pulverizing a quantity of water Black lime is quenched, then partially in sulfuric lime transformed to later a more intimate and faster connection with to achieve the plaster of paris, then the relevant filling material, which is made of sawdust, 'peat dust, Chaff, ashes, sand and so on (as required) can exist, admits and the same intimately mixed with the mixture. To do this, one then carefully mixes the one for this purpose Fired plaster and, if necessary, prepared with borax solution, which is immediately added the rest of the mass enters into an intimate connection and in a short time, with the whole mass poured into molds, completely hardened to stone. It will be noted that the use of the well-known, in the trade, located building plaster completely in the manufacture is excluded, since the same does not enter into any connection with the aforementioned mass, much less hardened.
Die Materialien können z. B. in folgenden Mengenverhältnissen zur Verwendung kommen: 50 1 Wasser, 7,5 kg hydraul. Schwarzkalk, pulverisirt, Y8 1 66gradige Schwefelsäure, ca. 8 kg Sägemehl, 35 kg fein gemahlener und gut gebrannter Gips oderThe materials can e.g. B. come in the following proportions for use: 50 1 water, 7.5 kg hydraul. Black lime, pulverized, Y 8 1 66-degree sulfuric acid, approx. 8 kg sawdust, 35 kg finely ground and well-burned gypsum or

18,5 kg Schlacke, 35 kg fein gemahlener und gut gebrannter Gips.18.5 kg of slag, 35 kg of finely ground and well-fired plaster of paris.
Es ist die Wirkung des gekennzeichneten Verfahrens eine ganz andere als diejenige der EinwirkungThe effect of the marked procedure is completely different from that of the Impact
1. einer Sulfitlösung auf bereits abgebundenen Gips, wobei die Sulfitlösung lediglich als Leitflüssigkeit für Härtungsmittel benutzt wird,1. a sulphite solution on already set plaster of paris, the sulphite solution only as a conductive liquid is used for hardening agents,
2. von schwefliger Säure, wodurch eine Zwischenbildung von Calciumsulfit in dem Gemisch von Kalk und gewöhnlichem Gips bewirkt und die Masse unter Oxydation in krystallisirten Gips verwandelt werden soll, während hier die innige Verbindung und vollständige Erhärtung, d. h. Krystallisirung der ganzen Masse durch sorgfältig gebrannten Gips erzielt wird.2. of sulphurous acid, causing an intermediate formation of calcium sulphite in the A mixture of lime and ordinary gypsum is brought about and the mass is to be transformed into crystallized gypsum by means of oxidation, while here the intimate connection and complete hardening, d. H. Crystallization of the whole mass is achieved by carefully fired plaster of paris.
Die Herstellung von Steinen aus einem Gemisch von Cement, Gips und Sand mit verdünnter Schwefelsäure zu einem Brei angerührt, ist zwar schon eine altbekannte (vergh Feichtinger, Mörtelmaterialien, Braunschweig 1885, Seite 421, Abs. 4 und 6), jedoch konnte dieses Gemisch nur unter Anwendung einer starken Pressung zu Steinen erhärtet werden; vorliegende Erfindung unterscheidet sich aber gerade dadurch von diesem Verfahren, dafs durch die Mischungsweise der Substanzen und durch Anwendung des gut gebrannten Gipses ohne Druck der Effect erzielt wird, indem die gemischte Masse, als steifflüssiger Brei in Formen gegossen, ohne jeglichen Druck oder Pressung in kurzer Zeit von selbst erhärtet und, an der Luft getrockne" eine harte, klingende Steinmasse bildet.The manufacture of stones from a mixture of cement, plaster of paris and sand with diluted Sulfuric acid mixed into a pulp is already a well-known one Feichtinger, Mortar Materials, Braunschweig 1885, page 421, Paragraphs 4 and 6), however, could this mixture can only be hardened into stones by applying strong pressure; However, the present invention differs from this process precisely in that through the way the substances are mixed and through the use of the well-fired plaster of paris without pressure the effect is achieved by adding the mixed mass, as a stiff, liquid pulp Molds cast, hardened by themselves in a short time without any pressure or pressure and, air-dried "forms a hard, sounding stone mass.
