Description

Verfahren zur Herstellung kalkgebundener Steine Zusatz zum Patent 830 023 Dein Patent 8,30 02,3 liegt die Erkenntnis züigrundc, da(3 bei der Verwendung von kalkhaltiger Braunkohlenasche als Bindemittel zur Vermeidung von Treiberscheinungen es erforderlich ist, den Löschproze13 nicht in der üblichen Weise heiAtmospli'ireiidru(-k, sondern bei Dampfdrü,-ken über Atmospl);irendruck durchzuführen, weil die Braunkohlenhe in der Feuerung einer erhel)lih höhuren Temperatur unterworfen war, als bei der normalen K;ilkl)rciiiiuiig angewandt zu \%-erden pflegt. Auch bei der Herstellung von kalkgebundenen Steinen, die als Zuschlagstoff Verbrennungsrückstände aus der Stciiikc)hleii- oder Braunkohlenfeuerun- eiltbahen, besteht dic (,(,fahr, da() ungenügend ge- löschte Bestandteile an Kall, oder Magnesia, die von den Verbrennungsrückständen mitgeführt werden, zu lästigen Treiberscheinungen Anlaß geben.A process for preparing kalkgebundener stones addition to Patent 830,023 Your Patent 8,30 02,3 is the recognition züigrundc as (3, it is necessary when using calcareous brown coal ash as a binder for the avoidance of drift phenomena, the Löschproze13 not in the usual manner heiAtmospli 'ireiidru (-k, but in the case of steam pressure, -ken above atmosphere); ireiidru to be carried out because the lignite in the furnace was subjected to a lighter higher temperature than with normal K; ilkl) normally used to earth . Also in the production of lime-bound stones which eiltbahen as aggregate combustion residues from the Stciiikc) hleii- or Braunkohlenfeuerun- consists dic (, (, driving, since () in- sufficient deleted components to Kall, or magnesia, carried along by the combustion residues will give rise to annoying driving phenomena.

I'm dem abzuhelfen, wird gemäß der vorliegenden Erfindung die Löschung bei Dampfdrücken über Atmosphärendruck auch angewandt auf Flugasche oder sonstige aus Verbrennungsrückständun genommene Zuschlagstoffe, wenn diese Zuschlagstolie Calciumcarbonat, Magnesiumoxyd o.dgl. Bestandteile enthalten oder aber enthalten können.To remedy this, according to the present invention, the deletion at vapor pressures above atmospheric pressure also applied to fly ash or others aggregates taken from combustion residues, if this aggregate foil Calcium carbonate, magnesium oxide or the like. Contain or contain components can.

li Eine solche Hochdrucklöschung kann sowohl angewandt werden bci einer Bindung durch bei normaler Temperatur gebrannten Kalk als auch dann" wenn wie im Hauptpatent kalkhaltige Braunk-ohlenasche als Bindemittel verwendet wird. Im letzteren Falle wird man Zuschlagstoff und Bindemittel zusammen dem Löschprozeß unterwerfen, während man bei Verwendung von normal gebranntem Kalk vorteilhaft den Zuschlagstoff und das Bindemittel getrennt, gegebenenfalls bei verschiedenen Drükken, löschen kann.li Such a high pressure extinguishing can be used both bci a bond through lime burnt at normal temperature as well as "if." as in the main patent, calcareous lignite ash as a binder is used. In the latter case, the aggregate and binder are combined subject to the slaking process while using normal quicklime Advantageously, the aggregate and the binder separately, optionally with different ones Press, can delete.
