Description

Herstellung von Zement aus Hochofenschlacke. Zusatz zum Patent 368268. Nach dem Hauptpatent sollen Zemente aus Hochofenschlacke dadurch hergestellt oder verbessert werden, daß Salzträger mit anregend wirkenden Salzen getränkt und dem Zement beigemahlen werden.Manufacture of cement from blast furnace slag. Addendum to patent 368268. According to the main patent, cements are to be made from blast furnace slag or be improved that salt carriers soaked with stimulating salts and the Cement to be ground.

Bei den neueren Untersuchungen des Erfinders hat sich nun herausgestellt, daß das Verfahren geeignet ist, nicht nur die Abbindezeit des Zementes zu verkürzen, sondern auch z. B. die Abbindezeit des Zementes zu verlängern, die Salzwasserbeständigkeit des Betons zu erhöhen oder sonstwie dessen Eigenschaften zu verändern, dadurch, daß man entsprechend wirkende Salze den Trägerstoffen einverleibt, die dann mit der Hochofenschlacke oder dem Zement, der aus der Hochofenschlacke hergestellt wird, vermahlen werden. So kann z. B. Ammoniumkarbonat zur Erhöhung der Salzwasserbeständigkeit oder bei i Umschlägern und Schnellbindern verzögernd wirkendes Salz genommen und auf diese Weise der Zement in seinen Eigenschaften weitgehend verändert werden. Auch festigkeitserhöhende oder überhaupt das Abbinden herbeiführende Salze können verwendet werden, so daß an Klinkerzusatz bei Hochofenzement gespart oder dieser ganz weggelassen werden kann.In the more recent investigations of the inventor it has now been found that the process is suitable not only to shorten the setting time of the cement, but also z. B. to extend the setting time of the cement, the salt water resistance to increase the concrete or otherwise change its properties, thereby that correspondingly acting salts are incorporated into the carrier substances, which then with the blast furnace slag or the cement produced from the blast furnace slag, be ground. So z. B. ammonium carbonate to increase salt water resistance or in the case of pouches and quick binders, taking a retarding salt and in this way the properties of the cement are largely changed. Salts that increase strength or even induce setting can also be used be used so that clinker additive is saved in blast furnace cement or this can be omitted entirely.

PATENTANSPRUCH: Verfahren zur Herstellung von Zement aus Hochofenschlacke nach Patent 368268, da durch gekennzeichnet, daß die dem Mahlgut zuzusetzenden Trägerstoffe mit Lösungen von die Abbindung verzögernden Salzen oder von dem Zement sonstwie verbessernden Salzen, wie Ammoniumkarbonat, getränkt werden. PATENT CLAIM: Process for the production of cement from blast furnace slag according to patent 368268, characterized in that the carrier substances to be added to the ground material are impregnated with solutions of salts that retard the setting or of salts that otherwise improve the cement, such as ammonium carbonate.
