Description

Herstellung von Baustoffen aus Asche. Die Erfindung betrifft ein Verfahren zur Herstellung von Mörtel, Zementersatz, Bausteinen u. dgl. aus Asche, insbesondere aus Braunkohlenasche.Manufacture of building materials from ashes. The invention relates to a method for the production of mortar, cement substitute, building blocks and the like from ashes, in particular from lignite ash.

Es ist an sich bereits bekannt, Braunkohlenasche zu .verwenden und dabei durch Zusätze die Sulfide oder ihre schädliche Wirkung zu beseitigen.It is already known per se to use and use lignite ash using additives to eliminate sulphides or their harmful effects.

Es ist bereits auch vorgeschlagen worden, nur Asche zu verwenden, die bei .Verbrennung von Braunkohle bei Temperaturen von über goo° entstanden ist, um die vorhandenen Sulfide zu zerstören oder deren Bildung zu verhindern.It has also been suggested to use only ashes, caused by the combustion of lignite at temperatures of over goo °, to destroy the sulphides present or to prevent their formation.

Da aber bekanntlich die Bindekraft der Braunkohlenasche mit auf dem Vorhandensein von Gips darin beruht, erscheint, es zunächst nicht zweckmäßig, sehr hohe Temperaturen anzuwenden, da dann der Gipst ;totgebrannt würde. Die wirtschaftliche Ausnutzung der Braunkohle aber erfordert die Anwendung möglichst hoher Temperaturen, so daß in vielen Fällen in der Braunkohlenasche der Gips mehr oder weniger totgebrannt sein wird; besonders wenn man berücksichtigt, daß die Braunkohle nicht verbrannt wird, um möglichst gipsreiche Asche zu liefern, sondern um damit einen möglichst hohen Heizgrad, also eine gute wirtschaftliche Ausnutzung zu erreichen.But since, as is well known, the cohesive power of lignite ash is also on the If plaster of paris is based on it, it does not appear to be very practical at first sight to use high temperatures as the plaster would then be burned to death. The economic However, the utilization of lignite requires the use of the highest possible temperatures, so that in many cases the gypsum in the lignite ash is more or less burned to death will be; especially when you consider that the lignite was not burned is to deliver ashes rich in gypsum as possible, but to provide you with as much as possible high degree of heating, i.e. to achieve good economic utilization.

Es ist nun an sich bekannt, daß totgegebrannter Gips durch Zusatz von Bisulfaten wieder verwendungsfähig wird.It is now known per se that burned to death plaster of paris by addition of bisulphates becomes reusable.

Es ist ferner bekannt, daß durch Zusätze von Bisulfat die Festigkeit des herzustellenden Produktes bedeutend verbessert wird.It is also known that the strength by adding bisulfate of the product to be manufactured is significantly improved.

Erfindungsgemäß wird nun aber vorgeschlagen, den Zusatz von Bisulfaten, insbesondere von Natriumbisulfat, dazu zu benutzen, um den totgebrannten Gips in allen Arten von Braunkohlenaschen wieder bindungsfähig zu machen.According to the invention, however, it is now proposed to add bisulfates, especially sodium bisulfate, to be used to break the dead-burned plaster of paris in to make all types of lignite ash binding again.

Auf diese Weise ist es möglich, insbesondere Braunkohlenasche aus hochwertigen Feuerungen zur Herstellung billiger und einwandfreier Baustoffe zu verwenden.In this way it is possible, in particular, from brown coal ash high-quality furnaces for the production of cheap and flawless building materials use.
