Description

Verfahren zur Herstellung eines hydraulischen Bindemittels aus Ölschieferschlacke. Zusatz zum Patent 411584. Das Hauptpatent 4[i584 betrifft ein Verfahren zur - Herstellung eines hydraulischen Bindemittels aus Ölschieferschlacke, das aus geringen Mengen von unter der Sinterungsgrenze gebranntem Mergel und gebranntem Ölschiefer bzw. gebranntem Schieferkoks besteht.Process for the production of a hydraulic binder from oil shale slag. Addition to patent 411584. The main patent 4 [1584 relates to a process for - production of a hydraulic binder made from oil shale slag, which is made from small quantities of marl burnt below the sintering limit and burnt oil shale or burned shale coke.

Die vorliegende Erfindung betrifft nun eine Ausgestaltung dieses Verfahrens. Sie bezweckt eine wesentliche Verbesserung des erzielten hydraulischen Bindemittels, und zwar insbesondere für solche Zwecke, bei denen die Verwendung im Wasser in Frage kommt. Die Verbesserung besteht darin, daß dem Gemisch aus Schieferschlacke und gebranntem Mergel noch Hochofenschlacke u. dgl. beigemengt wird, und zwar kann dieser Anteil bis zu etwa 5o Prozent der Gesamtmischung gehen. Durch diese Beimengung wird die Festigkeit bei Erhärtung an der Luft keineswegs vermindert, bei Erhärtung im Wasser dagegen ganz erheblich vermehrt. Außerdem wird die chemische Zusammensetzung des Bindemittels insofern günstiger, als eine Verminderung des Schwefelsäureanhydridgehalts eintritt. Dieser Vorteil ist darauf zurückzu., führen, daß die in Frage kommende Hochofenschlacke viel weniger Schwefelanhydri#l enthält als die ölschieferschlacke, so daß selbst bei Verwendung kalkreicher Mergel und sehr schwefelreicher ölschieferschlacke ein Bindemittel erhalten wird, welches allen Anforderungen an Beständigkeit in vollem Umfange genügt.The present invention now relates to an embodiment of this method. It aims to significantly improve the hydraulic binder achieved, in particular for those purposes where the use in the water is in question comes. The improvement is that the mixture of slate and slate blast furnace slag and the like are added to fired marl, and this can be done Share up to about 5o percent of the total mix. This admixture is the strength is in no way reduced when hardening in the air, when hardening in the Water, on the other hand, increased considerably. Also, the chemical composition of the binder in that it is more favorable than a reduction in the sulfuric acid anhydride content entry. This advantage is due to the fact that the in question Blast furnace slag contains much less sulfuric anhydride than oil shale slag, so that even when using lime-rich marl and very sulfur-rich oil slate slag a binder is obtained that fully meets all the requirements for durability Scope is sufficient.

Das Verfahren kann in beliebiger Weise durchgeführt werden, wie z. B. derart, daß der Ölschiefer und der Mergel, einzeln gebrannt, zusammengebracht und mit der Hochofenschlacke vermischt, oder aber, beide Stoffe zusammen gebrannt werden, ehe die Hochofenschlacke hinzugemengt wird. Anstatt Hochofenschlacke können auch andere hydraulische Zuschläge, wie Traß, gebrannter Ton o. dgl., verwendet werden.The method can be carried out in any manner, such as. B. such that the oil shale and marl, individually burned, brought together and mixed with the blast furnace slag, or else both substances are burned together before the blast furnace slag is added. Instead of blast furnace slag you can Other hydraulic aggregates, such as trass, burnt clay or the like, are also used will.

Dias Gemisch wird dann wieder in der bekannten Weise staubfein gemahlen.The mixture is then ground again as fine as dust in the known manner.
