PATENTAMT.PATENT OFFICE.
Der Carnaliit, dessen bedeutendstes bis jetzt bekanntes Vorkommen das von Stafsfurt und Leopoldshall ist, liefert beim Brennen mit thonerde-, kieselsaure- und kalkhaltigen Materialien einen vorzüglichen Cement.The Carnaliit, the most important occurrence of which is known up to now that of Stafsfurt and Leopoldshall is, delivers when firing with clay, silica and calcareous materials an excellent cement.
Er wird den anderen Rohmaterialien am besten in wässeriger Lösung in der Weise zugesetzt, dafs dieselben in fein zertheiltem Zustande trocken aufs Innigste gemischt und hierauf mit der Carnallitlösung zu einem streichrechten Teige angemacht werden. Doch kann man auch den Carnaliit in Pulverform mit den übrigen Rohmaterialien mischen und alsdann den Teig mit Wasser anmachen, oder bei geeigneten Vorrichtungen überhaupt das nasse Mischverfahren anwenden.It is best added to the other raw materials in an aqueous solution in such a way that that the same in finely divided condition, dryly mixed in the most intimate way, and then mixed can be made into a spreadable dough with the carnallite solution. But you can Mix the powdered carnalite with the other raw materials and then the dough mix with water, or with suitable devices even the wet mixing method use.
Aus dem Teige werden Ziegel geformt oder rundliche Stücke geballt, getrocknet, in den gewöhnlichen Cementbrennöfen gebrannt und hierauf zerkleinert und gemahlen.Bricks are formed from the dough or rounded pieces are balled, dried, in the ordinary Cement kilns burned and then crushed and ground.
Mischt man z. B. 100 kg Schlackenmehl von einer sehr' basischen Hochofenschlacke (circa 50 pCt. Kalkerde, 35 pCt. Kieselsäure und 9 pCt. Thonerde enthaltend) mit 15 kg Bauxit von circa 5opCt. Thonerde (s. D.R. P. No. 19800) und 135 kg Kalkstein oder Kreide und setzt diesem Gemisch 15 kg Stafsfurter Carnaliit in wässeriger Lösung zu, so erhält man nach dem angegebenen Verfahren einen sehr kalkreichen, dabei volumenbeständigen und vorzüglich erhärtenden Cement.If you mix z. B. 100 kg slag meal from a very 'basic blast furnace slag (approx 50 pct. Limestone, 35 pct. Silica and 9 pCt. Containing clay) with 15 kg of bauxite of about 5opCt. Clay (see D.R. P. No. 19800) and 135 kg of limestone or chalk and put 15 kg of Stafsfurt carnalite in this mixture aqueous solution, so one obtains a very lime-rich, volume-stable and excellently hardening cement.
Auch aus den Rohmaterialien, welche bei der gewöhnlichen Portland - und Roman - Cementfabrikation zur Verwendung gelangen, läfst sich durch Zusatz von Carnaliit ein hochwerthigeres Product erzielen.Also from the raw materials used in ordinary Portland and Roman cement production come to use, a higher quality can be obtained by adding carnaliite Achieve product.
Hier wird ebenfalls der Carnaliit am besten in Wasser- gelöst und in dieser Form dem Rohmaterial der Portland- oder Roman-Cementfabrikation zugesetzt; das Fabrikations verfahren bleibt dabei im- übrigen unverändert. In der Regel genügen 10 kg Carnaliit pro Tonne (= 170 kg) Cement, jedoch empfiehlt es sich, für jedes Rohmaterial das zweckmäfsigste Zusatzquantum durch Versuche besonders festzustellen.Here, too, the carnalite is best dissolved in water and, in this form, the raw material added to Portland or Roman cement manufacture; the manufacturing process otherwise remains unchanged. As a rule, 10 kg of carnalite per ton are sufficient (= 170 kg) cement, but it is recommended For each raw material, the most expedient additional quantity to be determined by experiments.
