Description
Verfahren zur Herstellung von Zement 'unter Verwendung insbesondere saurer Schlacken. Bei Herstellung von Hochofenzement war maxi gezwungen, als Schlackenanteile basische Schlacke zu verwenden, da saure Schlacken reaktionsträge sind, infolgedessen nur schlechte Festigkeiten ergeben. Man nimmt zur Herstellung des Hochofenzementes in der Regel einen möglichst hochkalkigen Klinker, um, die Reaktionsträgheit mancher Schlacken zu überwinden und zu guten Anfangsfestgkeiten zu kommen. Der Verwendung hochkalkiger Klinker sind aber sehr enge Grenzen gesetzt, denn, wenn auch Klinker verwendet werden können, die, allein° vermahlen, treiben würden, so kann doch der Kalkgehalt nicht ein gewisses, geringes Maß überschreiten, ohne daß ein Treiber erzielt wird.Process for the production of cement 'using in particular acid slags. During the production of blast furnace cement maxi was forced to use as slag proportions to use basic slag, since acidic slags are inert, as a result result in only poor strengths. One takes for the production of the blast furnace cement As a rule, a clinker that is as high-lime as possible, um, the inertia of some To overcome slag and to get a good start. Of use Highly limestone clinker, however, has very narrow limits, because, albeit clinker can be used which, if ground alone, would float, the Lime content does not exceed a certain, small level without a driver is achieved.
Das vorliegende Verfahren nun nimmt auch hochkalkigem Klinker jede Treibeigenschaft und vermittelt gleichzeitig eine in wissenschaftlicher Beziehung noch ungeklärte Einwirkung des Klinkers auf die Schlacke. Diese Reaktionen werden dadurch erzielt, daß ein Teil z. B. ein Viertel der Schlacke naß und der übrige Teil trocken in die Mühle eingebracht wird. Heißes Vermahlen ist hierbei von Vorteil und zweckmäßig. Das mit der Schlacke eingebrachte Wasser beruhigt den Klinker und schließt gleichzeitig die Schlacke auf. Durch diese Einwirkung ist es möglich, z. sehr kalkreiche Klinker zu verwenden, die zu hohen Festigkeiten führen und auch auf saure Schlacken günstig einwirken. Die Treibeigenschaft dieser Klinker wird durch die nasse Schlacke zerstört, und es wird möglich, Klinker zu verwenden, welche in bisherigem Betrieb uribrauchbar waren, da sie zu Treibern führten.The present method now also takes any high-limestone clinker Driving ability and at the same time conveys one in a scientific relationship as yet unexplained effect of the clinker on the slag. These reactions will be achieved in that a part z. B. a quarter of the slag wet and the rest Part dry is brought into the mill. Hot grinding is an advantage here and functional. The water brought in with the slag calms the clinker and opens up the slag at the same time. By this action it is possible, for. to use very lime-rich clinker, which leads to high strength and also have a beneficial effect on acidic slag. The blowing property of this clinker will destroyed by the wet slag, and it becomes possible to use clinker which were originally usable because they led to drivers.
2. sehr saure Schlacken zu verarbeiten, da die kalkreichen Klinker, denen durch das Verfahren die-Treibeigenschaft genommen ist, auch saure Schlacken in genügendem Maße zu Erhärtung anregen.2. to process very acidic slag, since the lime-rich clinker, which have lost their propellant properties as a result of the process, including acidic slag stimulate sufficient hardening.
