Verfahren der Herstellung von Trockenmörtel aus Kalk und Sand.Method of making dry mortar from lime and sand.
Patentiert im Deutschen Reiche vom 23. Oktober 1912 ab.Patented in the German Empire on October 23, 1912.
Gegenstand der Erfindung ist ein Verfahren der Herstellung von Mörtel aus Kalk und Sand, und zwar von Trockenmörtel, der hydraulische Eigenschaften hat, auch wenn nur gewöhnlicher Weißkalk Anwendung findet.The invention relates to a method of producing mortar from lime and Sand, from dry mortar that has hydraulic properties, even if only Ordinary white lime is used.
Die Neuerung besteht darin, Sand, der kohlensauren Kalk in irgendeiner Form enthält, mit gebranntem Kalk zu mischen, zersetzliche Chloride und Feuchtigkeit zuzuführenThe innovation consists in the use of sand, which contains carbonate of lime in some form, to mix with quick lime, add decomposable chlorides and moisture
»o und die Löschung in der Wärme vorzunehmen. Zu dem Zwecke wird die Masse in eine Trommel gebracht oder durch teilweise geschlossene trommelartige Räume hindurchgeführt. Wesentlich ist, daß die Löschwärme zusammengehalten oder von außen besonders Wärme zugeführt wird, damit eine Temperatur von 80 bis ioo° C sicher erzielt wird.»O and to carry out the extinguishing in the warmth. For this purpose, the mass is brought into a drum or partially closed drum-like spaces passed through. It is essential that the extinguishing heats held together or extra heat is supplied from the outside so that a temperature of 80 to 100 ° C is reliably achieved.
Am vorteilhaftesten verwendet man Sand, der mit Mergel oder kalkhaltigem Ton durchsetzt ist; ebenso eignen sich die mit zerriebenen Kalksteinen durchsetzten Diluvialsande oder überhaupt mit kohlensaurem Kalk vermischte Quarzsande, die gewöhnlich als Kalksande bezeichnet werden. Es kann auch Quarzsand genommen werden, dem künstlich Kreide oder Kalksteinmehl beigemischt ist.It is best to use sand interspersed with marl or calcareous clay is; The diluvial sands interspersed with crushed limestone are also suitable or quartz sands mixed with carbonate of lime, usually called lime sands are designated. You can also use quartz sand with artificially mixed with chalk or limestone powder.
Die für das neue Verfahren erforderlichen Chloride, z. B. Magnesiumchlorid, Kalziumchlorid, Aluminiumchlorid, Ammoniumchlorid, Eisenchlorid, wirken als Katalysatoren für die Umsetzung zwischen Ätzkalk und Kalziumkarbonat zur Bildung einer hydraulischen Doppelverbindung aus diesen beiden Körpern. Außerdem bedingen sie auch durch die mit den Löschdämpfen frei werdende Salzsäure eine gewisse Aufschließung des Sandes, die allerdings an sich bekannt ist.The ones required for the new procedure Chlorides, e.g. B. Magnesium chloride, calcium chloride, aluminum chloride, ammonium chloride, Iron chloride, act as catalysts for the conversion between quicklime and calcium carbonate to form a hydraulic double connection from these two bodies. In addition, they are also conditioned by having The hydrochloric acid released by the extinguishing vapors causes a certain breakdown of the sand, which, however is known per se.
Besonders muß hervorgehoben werden, daß das neue Verfahren eine vorteilhafte Verwertung der bisher in der Mörtelindustrie verworfenen tonigen Sande, soweit es sich bei diesen um kalkhaltigen Ton handelt, bringt.It must be particularly emphasized that the new process is an advantageous recovery the clayey sands previously discarded in the mortar industry, insofar as these are calcareous clay.
Bisher sind Chloride, besonders Kalziumchlorid, nur zur Verbesserung von Mörtelbildnern, nicht aber von Mörtel, der bereits Sand enthält, vorgeschlagen worden. So sollte Kalk mit Magnesium- oder Kalziumchloridlösung trocken gelöscht werden, um plastisches Kalkhydrat zu erhalten. Ferner wurde Chlorkalzium der Portlandzementrohmasse einverleibt und dem Brennprozeß mit ausgesetzt. Auch in einem anderen Fall aus der Portlandzementindustrie, wo das Chlorkalzium nicht nur der Portlandzementrohmasse vor dem Brennen, sondern unter Umständen auch den bereits gebrannten Klinkern beigemengt werden soll, kam es nur auf die Bildung eines Oxychlorides beim Abbinden hinaus.So far, chlorides, especially calcium chloride, have only been used to improve mortar formers, but not suggested by mortar which already contains sand. So should Lime can be extinguished dry with magnesium or calcium chloride solution to make plastic To obtain hydrated lime. In addition, calcium chloride was incorporated into the raw Portland cement and exposed to the burning process. Also in another case from the Portland cement industry, where the calcium chloride is not only in the raw Portland cement mass before it is fired, but possibly also in the already should be added to burnt clinker, it came only to the formation of an oxychloride when setting.
Die eigenartigen Verhältnisse beim Gegenstande der Erfindung, die Löschung unter Dampf und die Anwesenheit von kohlensaurem Kalk im Mörtel, damit durch die Chloride basisches Kalziumkarbonat entstehen kann, sind bisher nirgends angedeutet worden. Sie unterscheiden sich auch von der einmal vorgeschlagenen Verwendung von Salzsäure in der Kalksandsteinindustrie, wobei der mit Sand vermengte Kalk vor der Härtung durchThe peculiar circumstances in the subject matter of the invention, the deletion under Steam and the presence of carbonate of lime in the mortar, hence due to the chlorides alkaline calcium carbonate can arise have not yet been indicated anywhere. They also differ from the once suggested use of hydrochloric acid in the sand-lime brick industry, whereby the lime mixed with sand through before hardening
die Säure gelöscht und in einen besonders günstigen Hydratzustand übergeführt werden sollte.the acid should be quenched and converted into a particularly favorable state of hydration.
