Description

Verfahren zurVerarbeitung von Zementen In dem Patent 703 33$ wird ein Verfahren zur Verarbeitung von Zementen beschrieben, das durch einen Zusatz hähermolekularer hydroxylgruppenhaltiger wasserlöslicher Verbindungen zu der Zementmasse gekennzeichnet ist. Als insbesondere verwendbare Zusatzstoffe sind Derivate an sich wasserunlöslicher Alkohole angeführt, die infolge ihres Gehaltes an seiner Polyäthylenglykoläth #ergruppe wasserlöslich sind.Process for processing cements In the patent 703 33 $ a process for processing cements is described, which is characterized by the addition of higher molecular weight, hydroxyl-containing, water-soluble compounds to the cement mass. Particularly useful additives are derivatives of water-insoluble alcohols which are water-soluble due to their content in its polyethylene glycol ether group.

In weiterer Ausgestaltung dieser Erfindung wurde nun gefun@den"daB auch solch.eAllkoholderivate, die nicht infolge der mehrfachen Oxäthylierung des Alkohols, sondern infolge seiner Überführung in die Teilester mehrbasischer anorganischer Säuren wasserlöslich sind, sich mit gleichem Vorteil als Zementzusatzstoffe verwenden lassen. Als solche Verbindungen kommen insbesondere die Estersäuren in Betracht, die sich von höhermolekularen Fettalkoholen ableiten, z. B. dodecylalkohol:schwefelsaures Ammonium, stearylalkoholsehwefelsaures Natrium, isoheptylphosphorsaures Natrium, oleylphosphorsaures Kalium, dodecylphosphoritgsaures Natrium, das Natriumsalz des Phosphorsäuremonoesters von Palmlcernölfettsäureäthanolamid u. dgl. mehr. Beispiel Der aus Palmkernölfettsäure durch Reduktion gewonnene Lorolalkohol wird. in den sauren Schwefelsäureester übergeführt. Dias ifatriumsalz der Lorolalkoholschwefelsäure vermischt man in fein pulverisierter Form im Verhältnis r : Zoo mit Zement und setzt dann mit Sand oder Kies und Wasser in üblicher Weise die Betonmischung an. Beispielsweise verwendet man ein Gewichtsteil Lorolalkoholsulfat auf Zoo Gewichtsteile Portlandzement, 96o Gewichtsteile Flußsand und 93 Gewichtsteile Wasser. Unter Verwendung der gleichen Menge Wasser, die sonst zum Anmachen von Stampfbeton benötigt wird, entsteht infolge des zugegebenen Verflüssigungsmittels ein flüssiger Betonbrei, der sich z. B: als Gießbeton eignet oder durch Pumpen von der Mischmaschine zur Baustelle befördert werden kann:.In a further embodiment of this invention, it has now been found that such alcohol derivatives which are water-soluble not as a result of the multiple oxyethylation of the alcohol but as a result of its conversion into the partial esters of polybasic inorganic acids can be used with the same advantage as cement additives Particularly suitable compounds are the ester acids derived from higher molecular weight fatty alcohols, for example dodecyl alcohol: ammonium sulphate, sodium stearyl alcohol and sulfuric acid, sodium isoheptylphosphoric acid, potassium oleylphosphoric acid, potassium dodecylphosphoric acid, dodecylphosphoric acid monohydrate oil, sodium dodecylphosphoric acid monohydrate, and the sodium sulfate of sodium, for example, sodium dodecylphosphoric acid monohydrate, and the sodium sulfate of sodium phosphate monoethanol Lorolic alcohol obtained by reduction from palm kernel oil fatty acid is converted into the acidic sulfuric acid ester. The sodium salt of Lorolic alcohol sulfuric acid is mixed in finely powdered form in the ratio r: zoo with cement and then mixed t sand or gravel and water to mix the concrete in the usual way. For example, one part by weight of Lorol alcohol sulfate is used on Zoo parts by weight of Portland cement, 96o parts by weight of river sand and 93 parts by weight of water. Using the same amount of water that is otherwise required for mixing rammed concrete, a liquid concrete slurry is created as a result of the added liquefying agent. B: suitable as poured concrete or can be pumped from the mixer to the construction site.
