Description

Verfahren zur Behandlung von Zementrohmasse. Nach angestellten Beobachtungen kann in dem Verfahren des Patents 3088q.8, K1. 80b, statt des Tonerdechlorids auch Eisenchlorid verwendet werden; denn es treten bei Anwendung von Eisenchlorid oder einer Lösung dieses Salzes die gleichen Erscheinungen ein, nämlich: Entwicklung von Kohlendioxyd, Erhöhung der plastischen Beschaffenheit der Zement-Rohmehlmischung, poröse Beschaffenheit des Klinkers nach - raschem, gleichmäßigem Brande, leichte Mahlbarkeit des erbrannten Klinkers.Process for treating raw cement mass. After making observations can in the procedure of the patent 3088q.8, K1. 80b, instead of the alumina too Ferric chloride can be used; because it occurs when using ferric chloride or a solution of this salt has the same phenomena, namely: development of carbon dioxide, increasing the plasticity of the cement-raw meal mixture, Porous nature of the clinker after - rapid, even fire, light Grindability of the burned clinker.

Beide Salze verhüten auch das Zerrieseln des Zementes und des aus ihm hergestellten Betons.Both salts also prevent the cement from trickling away concrete made to him.

Ferner haben auch Mischungen aus Tanerdechlorid und Eisenchlorid bzw. Lösungen, die diese beiden Salze enthalten, dieselben Wirkungen.Furthermore, mixtures of tan earth chloride and iron chloride or Solutions containing these two salts have the same effects.

Solche Lösungen sind leichter und billiger herzustellen als die technisch reinen Salze, und die Zementfabriken sind in der Lage, sich die zur Ausführung des Verfahrcns erforderliche Tonerdechlorid - Eisenchlorid-Lösung selbst aus Abfallprodukten herzustellen r. Aus Kesselasche.Such solutions are easier and cheaper to manufacture than those technically pure salts, and the cement factories are able to produce the necessary to carry out the Process required alumina chloride - ferric chloride solution itself from waste products to manufacture r. Made from boiler ash.

Man sättigt zerkleinerte Kesselasche mit roher Salzsäure, hebt die Lösung vom Rückstande ab und stellt sie auf etwa ro Prozent Salzgehalt ein. ?. Aus Ton und Chlormagnesiumlauge. Man mischt Ton mit Chlormagnesiumlauge (Abfallprodukt der Chlorkaliumfabriken) im berechneten Verhältnis und brennt die Mischung im Feldbrandöfen bei möglichstem Luftabschluß.The crushed boiler ash is saturated with crude hydrochloric acid and the Remove the solution from the residue and adjust it to a salt content of about ro percent. ?. the end Clay and magnesium chloride solution. Mix clay with magnesium chloride solution (waste product of the potassium chlorine factories) in the calculated ratio and burns the mixture in the field fire oven with the best possible air exclusion.

Das Röstprodukt laugt man mit Wasser aus und stellt die Lösung auf etwa ro Prozent Salzgehalt ein.The roasted product is leached with water and the solution is set up about ro percent salinity.
