Die Erfahrung hat gelehrt, daß ein bloßes Mischen von Portlandzement und Faserstoffen keine innige Vermischung zwischen dem Faserstoffe und Portlandzement zuläßt. Alle Fasern besitzen eine sehr große Neigung aneinander zu haften. Diese Eigenschaft wird beim bloßen Durchmischen mit Zement nicht aufgehoben. Es war daher bisher nicht möglich, eine gleichmäßig feine Verteilung der Faserstoffe imExperience has taught that a mere mixing of Portland cement and pulps does not allow intimate mixing between the fiber and Portland cement. All fibers have a very great tendency to adhere to one another. This property becomes with the bare Mixing with cement is not canceled. It was therefore not previously possible to achieve a uniform fine distribution of fibers in the
ίο Zement zu erreichen. Dies ist nur möglich, wenn die Faserstoffe, in denen die Fasern noch nicht bloßgelegt sind, mit Zement zusammen trocken vermählen werden. Dabei werden die einzelnen Fasern bloßgelegt und 15 mit Zementstaub umhüllt. Ein Aneinanderballen der Faserstoffe ist daher aufgehoben. ■Die Verarbeitung des Faserzementes geschieht in der üblichen Weise.ίο to achieve cement. This is only possible when the fibers, in which the fibers are not yet exposed, together with cement be dry-ground. The individual fibers are exposed and 15 wrapped in cement dust. A clumping of the fibers is therefore eliminated. ■ The fiber cement is processed in the usual way.
Gegenüber dem üblichen Verfahren, dem Zement Faserstoffe, wie Asbest, Zellulose, ■ Schlackenwolleusw., beizumischen, unterscheidet sich die vorliegende Arbeitsweise dadurch, daß die Faserstoffe nicht nur lose miteinander gemischt werden, sondern daß die Faser im Augenblick der Freilegung Zement vorfindet, der dieselben in Gestalt einer Staubschicht umhüllt. Es ist auch versucht worden, Asbest und Zement im Holländer zu mischen, was jedoch den Nachteil hat, daß große Wassermengen zu bewältigen sind und die Mischung unmittelbar nach ihrer Herstellung verarbeitet werden muß. Auf Vorrat kann nicht gearbeitet werden. Anstatt Mischungen von Portlandzement und Faserstoffen zu verwenden, ist es auch möglich, Mischungen von Faserstoffen, Hochofenschlacke und gebranntem Kalk innig miteinander zu vermählen. Diese Mischung ist zwar weniger lange haltbar, jedoch weisen die daraus hergestellten Erzeugnisse Festigkeiten auf, die dem Portlandzementzusatz nicht nachstehen.Compared to the usual method, the cement fiber materials such as asbestos, cellulose, ■ Add slag wool, etc., the present working method differs in that the fibers are not only loosely mixed with one another, but that the fibers in the At the moment of exposure, he finds cement, which is in the form of a layer of dust enveloped. Attempts have also been made to mix asbestos and cement in Dutch what however, has the disadvantage that large amounts of water have to be handled and the mixture must be processed immediately after their production. It is not possible to work on stocks will. Instead of using mixtures of Portland cement and fiber, it is also possible to use mixtures of To grind fiber materials, blast furnace slag and quick lime together. This mixture does not have a long shelf life, but the ones made from it have Products have strengths that are no inferior to the Portland cement additive.
Die fertig, gemischte Masse kann, nachdem sie mit Wasser getränkt und durchgearbeitet ist, in beliebiger Weise von Hand oder maschinell verformt werden. Die Formlinge werden während des Trocknens wie andere aus Zement oder Mörtel hergestellte Waren behandelt und hierbei entweder der Luft oder der Einwirkung von Feuchtigkeit ausgesetzt, gegebenenfalls auch den in der Kunststein-Industrie üblichen Härteverfahren unterworfen.The ready, mixed mass can after being soaked with water and worked through is to be deformed in any way by hand or by machine. The briquettes are treated like other goods made of cement or mortar while drying and exposed either to the air or to the action of moisture, possibly also in the artificial stone industry subject to the usual hardening processes.
