Description

Dichtungsmittel für Zement oder Beton Um das Eindringen von Wasser in Zement-oder Betonkörper oder in einen Verputz aus diesen Stoffen zu verhindern bzw. auf- ein möglichst geringes Maß zu beschränken, hat man der Beton- oder Mörtelmischung bituminöse öl- oder seifenhaltige Stoffe zugesetzt, welche die Aufgabe haben, die Poren des Beton- oder Zementkörpers zu verstopfen und wasserabweisend zu machen.Sealant for cement or concrete To prevent water from entering in cement or concrete or in a plaster made from these substances or to limit it to the lowest possible level, one has to use the concrete or mortar mixture bituminous oil or soap-containing substances added, which have the task of To clog pores of the concrete or cement body and make them water-repellent.

Auch die Verwendung kolloidaler Magnesiumverbindungen neben Wasserglas, die zur Bildung von Magnesiumhydrat führt; wurde für den gleichen Zweck schon vorgeschlagen.Also the use of colloidal magnesium compounds in addition to water glass, which leads to the formation of magnesium hydrate; has already been proposed for the same purpose.

Die vorliegende Erfindung hat nun ein Dichtungsmittel für Zement und Beton zum Gegenstande, das die Abfälle der Sintermagnesitfabrikation einer neuen Verwendung zuführt. Diese Abfälle, welche bisher ein wertloser, auf Halden geworfener Fabrikationsabfall waren, enthalten häufig neben dem Magnesiumoxyd bzw. -hydroxyd geringe Mengen von Eisenhydroxyd und Tonerdehydrat, die ebenso wie das Magnesiumhydroxyd in wässeriger alkalischer Lösung sehr voluminöse flockenartige Niederschläge ergeben und sich daher als Dichtungsmittel für Zement oder Beton besonders eignen. Das Dichtungsmittel gemäß der Erfindung besteht aus einem Gemenge von Alkaliseife, hydratisierter Kieselsäure und hydratisierten, fein gepulverten, zweckmäßig windgesichtetenAlr fällen der Sintermagnesitfabrikation.The present invention now has a sealant for cement and Concrete is the subject of the waste from the sintered magnesite production of a new one Use. This waste, which was previously worthless, thrown on heaps Manufacturing waste were often contained in addition to magnesium oxide or hydroxide small amounts of iron hydroxide and alumina hydrate, as well as the magnesium hydroxide give very voluminous flaky precipitates in aqueous alkaline solution and are therefore particularly suitable as sealants for cement or concrete. The sealant according to the invention consists of a mixture of alkali soap, hydrated silica and hydrated, finely powdered, suitably wind-sighted alr cases of sintered magnesite manufacture.

Die Mischungsverhältnisse und Konzentrationen der zur Anwendung gelangenden Stoffe können entsprechend dem jeweilig gewünschten Grad der Wirksamkeit des Dichtungsmittels geändert werden. Im folgenden sei ein Beispiel für die Herstellung des Dichtungsmittels gegeben.The mixing ratios and concentrations of the used Fabrics can be made according to the particular degree of effectiveness of the sealant desired be changed. The following is an example of the manufacture of the sealant given.

r 1 verdünntes Wasserglas von etwa i2 bis i5° Be wird mit einem Gemenge von 120 g Leinöl und 12o cmg Kali- oder Natronlauge von etwa z5° Be vermischt. Sodann werden 400 em3 einer verdünnten Magnesium- oder Calciumchloridlösung von etwa z5° Be zugesetzt und schließlich 5oo g hydratisierte windgesichtete Abfälle der Sintermagnesitfabrikation unter kräftigem Umrühren eingetragen.r 1 diluted water glass of about 12 to 15 ° Be is mixed with a mixture of 120 g linseed oil and 12o cmg potash or sodium hydroxide solution of about z5 ° Be mixed. Then 400 em3 of a dilute magnesium or calcium chloride solution of about z5 ° Be added and finally 500 g of hydrated wind-sifted wastes from sintered magnesite manufacture entered with vigorous stirring.

Statt des Leinöls können auch andere billige Öle verwendet werden, wenn. dieselben nur möglichst einfach reit einem geringen Aufwand von Alkalien verseift werden können. Sofern es wünschenswert erscheint, kann auch den Magnesiumhydroxyden Kalkhydrat, Tonerdehydrat, Eisenhydroxyd oder hydratisierte Kieselsäure bzw. oxydische oder silikatische Verbindungen dieser Stoffe beigemengt werden. Versuche mit Betonkörpern, welchen ein Dichtungsmittel gemäß der Erfindung einverleibt wurde, hätten ergeben, daß die Betonkörper eine weitaus größere Widerste,## fähigkeit gegen das Eindringen vonaa@tj' aufwiesen wie Betonkörper, welche keinealei Zusatz eines Dichtungsmittels oder eines'@dEr bisher bekannten Dichtungsmittel erhalten hätten.Instead of linseed oil, other cheap oils can be used, if. the same can only be saponified as simply as possible with a small amount of alkalis can be. If it appears desirable, magnesium hydroxides can also be used Lime hydrate, alumina hydrate, iron hydroxide or hydrated silicic acid or oxidic or silicate compounds of these substances are added. try with concrete bodies into which a sealant according to the invention has been incorporated, would have shown that the concrete body has a much greater resistance, ## ability to the penetration of aa @ tj 'exhibited like concrete bodies, which do not have any addition of a Sealant or a '@ dEr previously known sealant would have received.
