Description

1Wörtel- oder Kunststeinmasse, bestehend aus Kalk, Sand und Schwefelsäure Die Erfindung bezieht sich auf eine Kalk-Sand-Mischung, welche sowohl als Mörtel als auch zur Herstellung von Kunststeinen u. dgl. geeignet ist. Derartige Kalk-Sand-Mischungen werden im allgemeinen in einem Mischungsverhältnis von einem Teil Kalk und höchstens acht Teilen Sand hergestellt. Sie sind jedoch infolge der hohen Kosten des Kalkes teuer und haben außerdem den Nachteil, daß sie nicht genügend schnell erhärten. Die Festigkeit des Endproduktes ist in der Hauptsache abhängig von der Menge des in ihm @enthaltenen Kalkes.1Wort or artificial stone mass, consisting of lime, sand and sulfuric acid The invention relates to a lime-sand mixture, which both as a mortar as well as for the production of artificial stones and the like. Such lime-sand mixtures are generally in a mixing ratio of one part of lime and a maximum of made eight parts of sand. However, they are due to the high cost of lime expensive and also have the disadvantage that they do not harden sufficiently quickly. The strength of the end product is mainly dependent on the amount of lime contained in it.

Es ist ferner bekannt, daß sich die Eigenschaften derartiger Kalk-Sand-Mischungen ohne Erhöhungen des Kalkgehaltes verbessern lassen, wenn man ihnen geringe Mengen Schwefelsäure oder Lösungen schwefelsaurer Salze zusetzt.It is also known that the properties of such lime-sand mixtures Without increases in the lime content can be improved if you give them small amounts Sulfuric acid or solutions of sulfuric acid salts are added.

Der Erfinder hat die überraschende Feststellung gemacht, daß durch Erhöhung des Schwefelsäurezusatzes über das seither gebräuchliche Maß der erforderliche Kalkgehalt verringert werden kann, ohne daß dadurch die Festigkeit der erhärteten Masse ungünstig beeinflußt wird. Die Kalk-Sand-Mischung nach der Erfindung enthält bei .einem Zusatz von 3 bis 5 % verdünnter Schwefelsäure (von 4 bis 6° B6) auf einen Teil Kalk je nach dem Verwendungszweck neun und mehr Teile Sand. Diese Mischung besitzt trotz des geringen Kalkgehaltes als Mörtel sehr gute Eigenschaften und ist, da sie schnell @erhärtet, zur Herstellung von Kunststeinen be- sonders geeignet.The inventor made the surprising discovery that by increasing the addition of sulfuric acid beyond what has been customary since then, the required lime content can be reduced without adversely affecting the strength of the hardened mass. With an addition of 3 to 5% dilute sulfuric acid (from 4 to 6 ° B6) to one part of lime, the lime-sand mixture according to the invention contains nine or more parts of sand, depending on the intended use. Despite the low lime content as mortar This mixture has very good properties and is, as it hardens quickly @, for the manufacture of artificial stones loading Sonder suitable.
