Description

Verfahren zur Herstellung einer zementähnlichen Masse. Bekannt ist zur Herstellung künstlichen hydraulischen - Gipsmörtels insbesondere das Brennen natürlichen Dihydrates, Anhydrides oder totgebrannten Gipses zusammen mit Kalkerden oder Kalk ausscheidenden .Stoffen.Process for the production of a cement-like mass. Is known for the production of artificial hydraulic - gypsum mortar especially the firing natural dihydrates, anhydrides or dead-burned gypsum together with lime earths or lime-separating substances.

Das Wesen der Erfindung besteht in der Hauptsache darin, daß natürlicher oder künstlicher Gips einschließlich Dihydrat (CaS0, 2H"0) mit sauren Salzen alkalischer oder erdalkalischer Metalle mit oder ohne Zusatz freier Säure oder Säure ausscheidender Stoffe sowie gegebenenfalls alkalischer Beimischungen-vermischt oder vermahlen wird. Hierbei ist der hydrierte Gips ohne Schwierigkeit und ohne die verhältnismäßig hohen Kosten eines Brennprozesses in einen hoch bindungsfähigen und festen Zement umzuformen.The essence of the invention consists mainly in the fact that it is more natural or artificial gypsum including dihydrate (CaS0, 2H "0) with acidic salts more alkaline or alkaline earth metals with or without the addition of free acid or acid precipitating Substances and optionally alkaline admixtures-is mixed or ground. Here, the hydrogenated gypsum is without difficulty and without the relatively high To convert the costs of a firing process into a highly bondable and solid cement.

Wertvoll für die Erfindung ist noch die Herstellung bestimmter Mischungen von hydriertem Gips und Anhydriden oder totgehrannteni Gips, indem sich hierdurch eine weitgehende Anpassung an verfügbare Rohstoffe und an die gewünschten besonderen Eigenschaften der Erzeugnisse durchführen l:ißt.The preparation of certain mixtures is also valuable for the invention of hydrogenated plaster of paris and anhydrides or dead gypsum by doing this an extensive adaptation to available raw materials and to the desired special ones Properties of the products carry out: eats.

Die Vermischung reit den Säurezuschlägen kann auf trockenem Wege durch gemeinsames @'erniahlen oder auch in wiißr iger Lösung erfolgen, indem die Gipsstoffe in Wasser verrührt und die Zuschläge zugesetzt werden.The mixing of the acid additives can be done in a dry way Common @ 'niahlen or also take place in aqueous solution by adding the plaster of paris stirred in water and the additives are added.

Ein (iil)sin<irtel großer Bindefähigkeit ergibt sich nach dem neuen Verfahren beispielsweise wie folgt. Natürlicher Gips, wie Alabaster (Ca SO., + 2H20), wird mit o,2 bis o,5 (oder mehr) Gewichtsprozenten von Natrium- oder Kaliumbisulfat gemeinsam aufs feinste vermahlen. Oder das fein vermahlene Alabasterpulver wird mit 15 bis 2o Gewichtsprozenten Wasser verrührt, in dein 0,2 bis 0,5 und mehr Gewichtsprozente vom Gipsgewicht an -Natrium- oder Kaliumbisulfat enthalten sind. Ein derartiger Gipsmörtel kann mit -ganz erheblichen Mengen von Sandbeimischung verwendet werden.An (iil) sin <irtth of a large binding capacity results from the new method, for example, as follows. Natural plaster of paris, such as alabaster (Ca SO., + 2H20), is finely ground together with 0.2 to 0.5 (or more) percent by weight of sodium or potassium bisulfate. Or the finely ground alabaster powder is mixed with 15 to 20 percent by weight of water, which contains 0.2 to 0.5 and more percent by weight of the gypsum weight of sodium or potassium bisulfate. Such a gypsum mortar can be used with quite considerable amounts of sand admixture.

Man kann auch feinst vermahlenen natürlichen Gips zuerst mit natürlichem Anhydrid (CaS0,) oder totgebranntem Gips in Pulverform in verschiedenen Verhältnissen vermischen und dies dann mit o,2 bis o,5 und mehr Gewichtsprozenten \ätriumbisulfat bzw. -Natrium- oder haliumstilfat mit oder ohne Anwesenheit von Säuren zusammenmischen.You can also use finely ground natural plaster of paris first with natural Anhydride (CaS0,) or dead-burned plaster of paris in powder form in different proportions mix and then mix it with 0.2 to 0.5 percent by weight of \ atrium bisulfate Mix together sodium or halium stilfate with or without the presence of acids.
