Description

Verfahren zur Herstellung von Zementen. Die Erfindung bezweckt, aus den bisher wertlosen Zink-, Blei- und Silberschlacken sowie aus den Schlacken, die bei der Verarbeitung von Eisen, beispielsweise bei der Herstellung von Temperguß, sich ergeben, einen brauchbaren Zement bzw. Mörtel auf einfachem und billigem Wege darzustellen, was bisher nicht bekannt war.Process for the production of cements. The invention aims from the so far worthless zinc, lead and silver slag as well as from the slag that in the processing of iron, for example in the manufacture of malleable cast iron, result, a usable cement or mortar in a simple and cheap way to represent what was previously unknown.

Die Erfinder haben gefunden, daß zementfreie Mischungen dieser Schlacken in wassergranuliertem, trockenem Zustande mit gebranntem, nicht gelöschtem Kalk gute Zemente bzw. Mörtel darstellen.The inventors have found that cementless mixtures of these slags in a water-granulated, dry state with burnt, not slaked lime represent good cements or mortars.

Bei nicht zu geringem Kalkgehalt der Schlacke sind die durch die obige Mischung erzielten Zemente normengemäß. Die wassergranulierten Schlacken werden getrocknet, wobei jedoch zweckmäßig Temperaturen, bei denen die Schlacken bereits entglasen, vennieden werden. Sie werden dann mit dem gebrannten Kalk zusammen vermahlen.If the lime content of the slag is not too low, they are due to the above Mixture achieved cements in accordance with the standards. The water-granulated slags are dried, but expedient temperatures at which the slags are already deglass, be vennied. They are then ground together with the quick lime.
