Description

Verfahren zur Herstellung von weißem Schlackenzement. Es ist bekannt, dem fertigen Schlackenzement, welcher aus nasser Hochofenschlacke durch Vermischen mit gebranntem ungelöschten Kalk entstanden ist, nach der Fertigstellung noch tonende- und kieselsäurehaltige Materialien beizumischen, welche an sich keine Zementeigenschaften haben. Hierdurch soll eine Verbesserung des Schlackenzements erreicht werden. Im günstigsten Fall ist dies aber nur in ganz geringem Maße zutreffend.Process for the production of white slag cement. It is known, the finished slag cement, which is made from wet blast furnace slag by mixing with burnt, unslaked lime, after completion still clay-tone and to mix in siliceous materials, which per se have no cement properties to have. This is intended to improve the slag cement. in the In the best case scenario, however, this is only true to a very limited extent.

Es wurde nun gefunden, daß eine starke Verbesserung der Eigenschaften von weißem Schlackenzement erreicht wird, wenn der Zusatz von möglichst farblosen kieselsäurehaltigen Mineralien nicht zu dem fertiggestellten Schlackenzement erfolgt, sondern bereits während der Herstellung des SC'hlackeniemeritS aus nasser weisser Hochofenschlacke und gebranntem weißen Kalk.It has now been found that a great improvement in properties of white slag cement is achieved when the addition of as colorless as possible siliceous minerals are not added to the finished slag cement, but already during the production of the sc'hlackeniemeritS from wet white Blast furnace slag and quick white lime.

Bei der hohen Temperatur, welche durch das Ablöschen :des gebrannten Kalkes infolge der Anwesenheit -der nassen weißen Schlacke in der Mischtrommel entsteht, scheint der Ätzkalk eine aufschließende Wirkung auf diese Zusätze auszuüben" so daß Körper aus demselben entstehen, welche zementartig sind.At the high temperature caused by the extinguishing: the fired Lime is created as a result of the presence of the wet white slag in the mixing drum, the quick lime seems to have a revitalizing effect on these additives "so that bodies arise from it which are cement-like.

Die weitgehende Änderung der Eigenschaften dieser kieselsäurehaltigen Mineralien durch das vorliegende Verfahren erhellt daraus, daß z. B. Geyserit hierbei viel leichter mahlfähig wird. Bei Anwendung von Talkum an Stelle von Geyserit entsteht ein Schlackenzement von gewisser Wasserdurchlässigkeit sowie von großer Dichte und Politunfähigkeit.The extensive change in the properties of these silicic acid Minerals by the present process is evident from the fact that e.g. B. Geyserite here becomes grindable much more easily. If talc is used instead of geyserite a slag cement of a certain water permeability as well as of high density and Political incapacity.
