Description
Es ist bekannt, dass man Formsteine unter Benutzung von Schlacken durch Zumischen von Zement herstellen kann. Der Verbrauch an Zement hängt dabei von der gewünschten Festigkeit ab.It is known that molded bricks can be produced using slag by adding cement. The consumption of cement depends on the desired strength.
Bei gewissen Braunkohlensorten, z. B. aus dem Helmstedter Revier, sind von Natur aus Stoffe vorhanden, die infolge des Glühprozesses auf dem Rost einer Kesselanlage als Bindemittel wirken können. Schlacken aus derartigen Brennstoffen haben daher von sich aus eine gewisse Bindefähigkeit, so dass sie z. B. eine harte, betonartige Oberfläche bilden, wenn man sie zum Planieren von Wegen, Plätzen und dergleichen benutzt. Es sind Versuche gemacht worden, diese Eigenschaften durch Zumischen von Zement soweit zu verbessern, dass genügend feste Steine hergestellt werden können, jedoch bewirkt der Umstand, dass die Schlacke 4% und mehr Schwefelverbindungen enthält, die bekannte Erscheinung des Treibens, so dass derartige Steine von selbst zerfallen.With certain types of lignite, e.g. B. from the Helmstedter Revier, substances are naturally present that can act as binders as a result of the annealing process on the grate of a boiler system. Slags from such fuels therefore have a certain binding capacity by themselves, so that they can, for. B. form a hard, concrete-like surface when used for leveling paths, squares and the like. Attempts have been made to improve these properties by admixing cement to such an extent that sufficiently strong stones can be produced, but the fact that the slag contains 4% or more sulfur compounds causes the well-known phenomenon of drifting, so that such stones from disintegrate themselves.
Nimmt man jedoch anstelle von Zement Bindemittel, die durch den Schwefelgehalt der Schlacke nicht beeinträchtigt werden, wie gebrannten Gips oder gelöschten Kalk, so genügen nur geringe Zuschläge, um einen genügend festen Stein zu erzielen. Da die Schlacke von dem Kesselbesitzer in der Regel kostenlos abgegeben wird, hat ein solches Herstellungsverfahren eine grosse Wirtschaftlichkeit.However, if you use binding agents instead of cement, which are not affected by the sulfur content of the slag, such as burnt gypsum or slaked lime, only small aggregates are sufficient to achieve a sufficiently solid stone. Since the slag is usually given away by the boiler owner free of charge, such a production process is very economical.
