Description

Verfahren zur Herstellung von Kunststeinen aus Ölschieferschlacke. Die bisher üblichen Verfahren der Schiefersteinfabrikation waren sehr unvollkommen. Die Schieferschlacke enthält gebrannten Kalk und Sulfide in ganz ungleichmäßiger Verteilung und ist deshalb nicht raumbeständig. Steine aus solcher Schlacke zeigen gefährliche Treiberscheinungen.Process for the production of artificial stones from oil slate slag. The previously common methods of slate production were very imperfect. The slate contains quick lime and sulphides in a very uneven manner Distribution and is therefore not spatially stable. Show stones made from such slag dangerous driving phenomena.

Dieses Treiben bleibt zwar aus, wenn man für die Steinherstellung Schlacke verwendet, die mehrere Monate oder sogar jahrelang vorher im Freien gelagert wurde, was aber in der Praxis wirtschaftlich nicht durchführbar ist. Dabei gehen zudem auch die wertvollen hydraulischen Eigenschaften verloren und man braucht als Ersatz dafür erhebliche Mengen von Zement oder anderen teuren Bindemitteln. Diese können überdies in Wechselwirkung mit dem in der Schlacke enthaltenen Gips wiederum ein Treiben hervorrufen.This hustle and bustle does not occur if one is involved in stone production Used slag that was previously stored outdoors for several months or even years which, however, is not economically feasible in practice. Go there in addition, the valuable hydraulic properties are lost and you need as Substitute substantial amounts of cement or other expensive binders. These can also interact with the gypsum contained in the slag cause a hustle and bustle.

Durch vorliegende Erfindung ist es ermöglicht, auf technisch sehr einfache Weise raumbeständige Steine gegebenenfalls ganz ohne fremdes Bindemittel herzustellen. Im groben Teil werden die schädlichen Bestandteile schon durch kurze Lagerung im durchfeuchteten Zustand zerstört, im feingemahlenen Teil werden kleinere Mengen Kalk und Sulfiden durch die mit dem Feinmahlen verbundene gleichmäßige Verteilung, nötigenfalls auch durch geeignete Zuschläge unschädlich gemacht. Die nach vorliegender Erfindung hergestellten'Steine sind billiger herzustellen und zugleich weit besser als die bisherigen. Das Verfahren vorliegender Erfindung beseitigt die Gefahr des Treibens vollständig und zudem in einer technisch überaus einfachen Weise und beruht in der Erkenntnis der Ursachen und der. Wasserdurchlässigkeit der Schieferschlacken. Es besteht im wesentlichen darin, daß die groben Teile- der Schlacken vor ihrer Verarbeitung zii Kunststeinen systematisch mit Wassergemischt werden. Es wird dadurch erreicht, daß schon in diesem Stadium der Kunststeinherstellung ein Löschen des Kalkes stattfindet, welches dann aber keinerlei schädliche Folgen hat, und ferner, daß auch der Kalk nicht nur späterhin keinerlei Wirkung mehr auszuüben vermag, sondern im Gegenteil die Vorteile seiner Beifügung in vollem Umfang zur Geltung bringt.The present invention makes it possible, technically very much simple, volume-stable stones, if necessary without any external binding agent to manufacture. For the most part, the harmful components are already briefly removed Storage destroyed in the moistened state, in the finely ground part it becomes smaller Quantities of lime and sulphides due to the even distribution associated with fine grinding, if necessary also rendered harmless by means of suitable supplements. The following Invention made stones are cheaper to manufacture and at the same time far better than the previous ones. The method of the present invention eliminates the risk of Driving completely and also in a technically extremely simple way and is based in knowing the causes and the. Water permeability of the slate slag. It consists essentially in the fact that the coarse parts - the slag in front of it Processing zii artificial stones are systematically mixed with water. It becomes through it achieved that already at this stage of the production of artificial stone a deletion of the Limescale takes place, which then has no harmful consequences, and furthermore, that not only can the lime not have any effect afterwards, but on the contrary, it fully brings out the benefits of its inclusion.

Das Verfahren wird zweckmäßig derart durchgeführt, daß die vorzerkleinerte Schlacke durch ein Sieb von etwa z bis a mm Maschenweite abgesiebt wird. Das Siebfeine wird staubfein gemahlen und nötigenfalls mit geeigneten Zusätzen versehen, es dient als Bindemittel. Der grobe Teil, der den Füllstoff abgibt, wird gründlich mit Wasser durchfeuchtet und in diesem Zustand etwa eine Woche lang gelagert, so daß sämtlicher im Schiefer enthaltener Kalk unschädlich gemacht werden kann.The process is expediently carried out in such a way that the pre-crushed Slag is sieved through a sieve with a mesh size of about z to a mm. The fine screen is ground to a fine dust and, if necessary, provided with suitable additives, it serves as a binder. The coarse part that gives off the filler is rinsed with water soaked and stored in this state for about a week, so that all Lime contained in the slate can be rendered harmless.

a Gleichzeitig werden durch dieses Verfahren die Sulfide unschädlich gemacht, welche in vielen Schieferschlacken vorhanden sind und durch ihre Oxydation ebenfalls ein Treiben hervorrufen können. Diese Sulfide, die in trockenem Zustande haltbar sind, oxydieren sich aitalich, wenn die durchfeuchtete Schlacke vor der Verarbeitung zu Steinen eine Zeitlang geit wird.a At the same time, this process renders the sulfides harmless made, which are present in many slag slag and through their oxidation can also cause a hustle and bustle. These sulfides that are in dry Conditions are durable, aitalich are oxidized if the moistened slag before the Processing into stones will be done for a while.

Das Ablöschen des Kalks und die Zerstörmq der Sulfide kann noch wesentlich dadurch beschleunigt werden, daß man zum Durchfeuc#ten der Schlacke heißes Wasser oder Dampf verwendet.The quenching of the lime and the destruction of the sulphides can still be significant be accelerated by the fact that hot water is used to moisten the slag or steam is used.
