Description
Verfahren zur Herstellung selbst erhärtender Massen In dem Patent 8:59426 ist ein, Verfahren zur Herstellung selbst erhärtender Massen beschrieben, nach dem Flugaschen, wie sie bei der Wärmeerzeugung aus Industrieanlagen anfallen, und Abfallkalkschlämme von der Zersetzung von Calciumcarbid miteinander vermischt werden.Method of making self-setting compositions In the patent 8: 59426 describes a process for the production of self-hardening compositions, after the fly ash, as it occurs when generating heat from industrial plants, and waste lime sludge from the decomposition of calcium carbide mixed together will.
Bei der weiteren Ausgestaltung des Verfahrens nach dem Patent 859 426 wurde gefunden, daß eine außerordentliche Erleichterung in der Verarbeitung der Mischungen aus Abfallkalkschlämmen und Flugaschen erreicht werden kann, wenn man vor, bei oder nach der Vermischung der Bestandteile noch etwas Alkalilauge, zweckmäßig in Form einer Lösung von 3o bis 40 % Gehalt an: Alkalihydroxyd, zugibt. Die Plastizität der mit Alkalilauge gemischten Massen: ist erheblich gröiß@er als ohne diesen Zusatz und erlaubt vor allen Dingen die Verarbeitung der Massen auf der Strangpresse, während man sonst gezwungen ist, mit Schlagpressen oder mit hydraulischen Pressen zu arbeiten.In the further development of the process according to the patent 859 426 it was found that an extraordinary simplification in the processing of the mixtures of waste lime sludge and fly ash can be achieved if you add a little alkali lye before, during or after the mixing of the constituents, expediently in the form of a Solution of 3o to 40% content of: alkali hydroxide, adds. The plasticity of the masses mixed with alkali lye: is considerably greater than without this addition and, above all, allows the masses to be processed on the extrusion press, while otherwise one is forced to work with impact presses or hydraulic presses.
Überraschenderweise hat sich außerdem ergeben, daß, durch den Alkalihydroxydzusatz nicht nur die Verarbeitbarkeit der Mischungen ganz erheblich verbessert wird, sondern daß auch die daraus hergestellten Formkörper nach dem Erhärten ganz erheblich bessere mechanische Eigenschaften, insbesondere höhere Druckfestigkeit und Zugfestigkeit, aufweisen. So ist es beispielsweise möglich, durch einen Zusatz von etwa 2'/o an 35o/oi.ger Natronlauge zu einer Mischung aus zwei Gewichtsteilen Abfallkalkschlamm und einem Gewichtsteil Flugasche eine Erhöhung der Druckfestigkeit und der Zugfestigkeit um bis zu Zoo 0/ö zu erreichen.Surprisingly, it has also been found that, by the addition of alkali hydroxide not only the The processability of the mixtures has been considerably improved becomes, but that also the molded bodies produced therefrom after hardening completely Significantly better mechanical properties, especially higher compressive strength and tensile strength. It is possible, for example, by adding from about 2% to 35% sodium hydroxide solution to a mixture of two parts by weight Waste lime sludge and one part by weight of fly ash increase the compressive strength and the tensile strength to reach up to zoo 0 / ö.
