Description

Verfahren zur Verbesserung von Mörtelbildnern und Mörtel. Es ist bekannt, Mörtelbildner und Mörtelmassen, insbesondere Portlandzementmassen, mit rotem Eisenoxyd zu färben. Hierbei ist das Eisenoxyd nur als Farbstoff gebraucht, und hat man zwecks Ersparnis an dem teuren Farbstoff und zur Vermeidung unerwünschter Einwirkungen auf den Zement, mit denen man rechnete, nur mit geringen Zusatzmengen gearbeitet.Process for improving mortar formers and mortars. It is known, Mortar formers and mortar compounds, in particular Portland cement compounds, with red iron oxide to color. Here the iron oxide is only used as a dye, and is used for this purpose Saving on the expensive dye and avoiding undesirable effects only worked with small additional amounts on the cement, which was expected.

Es ist ferner schon vorgeschlagen worden, zur Erhöhung der Festigkeit unter anderem fein gemahlene Eisenoxyde dem Zementmörtel beizumischen. Doch handelt es sich auch in diesem Falle nur um die Zugabe geringer Mengen, also um die Verwendung von Eisenoxyd als Zuschlag. Überraschenderweise hat sich nun gezeigt, daß größere Mengen Eisenoxyde, wie sie in der Technik vielfach abfallen, ganz abgesehen von ihrer Farbwirkung, also auch nicht rotgetönte, außerordentlich günstige Wirkungen ausüben. Es erwies sich als möglich, sehr große Mengen von Eisenoxyd, etwa 5o Prozent, einzuarbeiten, wobei die Eigenschaft des Mörtels sogar verbessert wurde, höhere Festigkeit und Dichtigkeit erreicht wurde.It has also been proposed to increase strength among other things, add finely ground iron oxides to the cement mortar. But act In this case, too, it is only a question of adding small amounts, that is to say of use of iron oxide as a supplement. Surprisingly, it has now been shown that larger Amounts of iron oxides, as they often fall off in technology, not to mention their color effect, so also not red-tinted, extraordinarily favorable effects exercise. It was found possible to use very large amounts of iron oxide, about 50 percent, incorporated, the property of the mortar was even improved, higher Strength and tightness was achieved.

Gegenstand der vorliegenden Erfindung ist demgemäß die Verbesserung von Mörtelbildnern und Mörtel durch Zugabe von großen Mengen von Eisenoxyden.The present invention accordingly relates to the improvement of mortar formers and mortars by adding large amounts of iron oxides.

Die weitere Forschung hat ergeben, daß mit dem Eisenoxyd zusammen zweckmäßig Sulfate, und zwar auch in größerer '.Menge, eingearbeitet werden können.Further research has shown that together with the iron oxide expediently sulfates, even in larger quantities, can be incorporated.

Als solche Sulfate kommen in erster Linie Calciumsulfat in Frage. Man vcnnvendet also ein Gemenge von Eisenoxyden und Gips, dem außerdem auch noch Tonerdeverbindungen, z. B. Ton, beigegeben werden.Calcium sulphate is primarily suitable as such sulphate. So a mixture of iron oxides and gypsum is used, and that too Alumina compounds, e.g. B. clay, be added.

Das Eisenoxyd kann in der Form des caput mortuum, aber auch als Eisenoxydoxvdul, als Rösterz üsw. genommen werden.The iron oxide can be in the form of the caput mortuum, but also as iron oxide as roasting oil be taken.

In jedem Falle ist es vorteilhaft, die verwandten Eisenoxyde bzw. Eisenoxvdsulfatgemische zunächst längere Zeit in einer feuchten Atmosphäre lagern zu lassen, weil dadurch die hy draulifizierende Wirkung gefördert wird.In any case, it is advantageous to use the iron oxides or First store iron oxide sulphate mixtures in a humid atmosphere for a longer period of time to leave, because this promotes the hydraulic effect.

Beispielsweise vermengt man Zement mit 3o bis roo Teilen von Eisenoxyd oder Eisenoxyd und Gips, die feucht gelagert wurden, an deren Stelle auch gipshaltige Abbrände treten können.For example, one mixes cement with 30 to 100 parts of iron oxide or iron oxide and plaster of paris which have been stored moist, and plaster of paris in their place Burns can occur.

An der Neuerung ist nicht nur die verbessernde Wirkung der Eisenoxyde verblüffend, sondern auch der fördernde Einfluß der Sulfate. Durch die große Menge Eisenoxyd kommen anscheinend die ungünstigen Wirkungen von Gips auf Zement zur Aufliebung, denn es ist möglich, derartige Gemische mit einer beträchtlichen Menge Gips auch bei Portlandzementmörtel anzuwenden, wobei ebenfalls die angedeutete Verbesserung erreicht wird und Schädigungen nicht zu beobachten waren.The innovation is not only due to the improving effect of the iron oxides amazing, but also the beneficial influence of sulfates. Because of the large amount Iron oxide apparently the adverse effects of plaster of paris on cement to love, because it is possible to use such mixtures with a considerable amount of plaster of paris too to be used with Portland cement mortar, with the indicated improvement as well is reached and no damage was observed.
