Description
Verfahren zur Herstellung von Mauersteinen u. dgl. aus porösem material. Man kennt bereits mehrere Verfahren, um Mauersteine u. dgl. aus porösem Material herzustellen. Bei ihnen wird meistens das Ausgangsmaterial von den Bestandteilen befreit, die den für Mauersteine u. dgl. erforderlichen Eigenschaften äbträglich sind, und mit einem Bindemittel gemischt, dessen Zusammensetzung sich nach der chemischen Beschaffenheit des Ausgangsmaterials richtet. Das so gebildete Gemisch wird alsdann durch Stampfen und Pressen zu Mauersteinen o. dgl. verarbeitet, die durch nachfolgendes Abbinden die :erforderliche Festigkeit und Härte annehmen.Process for the production of bricks and the like from porous material. Several methods are already known for making bricks and the like from porous material to manufacture. Most often they are the starting material of the constituents exempted that adversely affect the properties required for bricks and the like are, and mixed with a binder, the composition of which depends on the chemical The nature of the source material. The mixture thus formed is then Processed by stamping and pressing into bricks o Setting that: take on the required strength and hardness.
Keines der älteren Verfahren berücksichtigt jedoch die Kapillarität des porösen Ausgangsmaterials, d. h. das Vorhandensein feinster Kanäle -und Poren innerhalb desselben, die die Möglichkeit bieten, das Bindemittel in die Poren und Kanäle eindringen sowie gegebenenfalls in. ihnen chemische Verbindungen bilden zu lassen.However, none of the older methods take capillarity into account the porous starting material, d. H. the presence of the finest channels and pores within the same that offer the opportunity to get the binder into the pores and Penetrate channels and, if necessary, form chemical compounds in them permit.
Gemäß der Erfindung wird diese Möglichkeit dadurch ausgenutzt, daß das poröse Material in trockenem `Zustande mit einem feinkörnigen, Sand- oder schlammartigen Bindemittel vermischt wird, das Wasser im Lberschuß :enthält. Das poröse Material entzieht dabei das Wasser mit überraschender Geschwindigkeit dem Bindemittel, das sich alsdann nicht nur auf der Oberfläche, sondern auch innerhalb der Poren abgelagert und gegebenenfalls eine chemische Verbindung mit dem einen :öder anderen* Bestandteil des Ausgangsmaterialseingeht.According to the invention, this possibility is used in that the porous material in the dry state with a fine-grained, sand- or mud-like one Binder is mixed, the water in excess: contains. The porous material removes the water from the binding agent at a surprising rate then deposited not only on the surface but also within the pores and possibly a chemical compound with one: or the other * component of the starting material.
Nach dem neuen Verfahren lassen sich grundsätzlich beliebige poröse Materialien zum Herstellen von Mauersteinen u. dgl. verwenden, :ohne Rücksicht darauf, ob es sich um ein natürliches oder um :ein Mineral handelt, das bereits irgendeiner Verarbeitung unterworfen war. Für den letzterem Fall kommen insbesondere ölschieferschlacken, d. h. Schlacken des bituminösen Ölschiefers, dem der Bitumengehalt vorher entzogen worden war, sowie Kohlenschlacken in Betracht, die nicht bis zur Schmelztemperatur erhitzt waren.In principle, any porous Use materials for making bricks and the like: regardless of whether whether it is a natural or: a mineral that already has any Processing was subject. In the latter case, oil shale slags are particularly useful, d. H. Slag from the bituminous oil shale from which the bitumen content was previously removed had been considered, as well as coal slags that did not reach the melting temperature were heated.
Nach dem neuen Verfahren können auch solche poröse Ausgangsmaterialien Verwendung finden, die :einen reichen Gehalt an Kieselsäure haben. Dieser Gehalt beträgt z. B. bei gewissen ölschieferschlacken ,1o bis 8o Prozent. Auch in anderen Vorkommen ist ein Gehalt an Kieselsäure von etwa 2o bis 4.o Prozent oder mehr keine Seltenheit. Zur Herstellung druckfester Steine aus solchen Materialien bedarf :es des Zusatzes von Kalk, der mit der Kieselsäure sich hydraulisch veri haltende Verbindungen eingeht, während er nach den bisher bekannten dies nicht tut und bei reichlicher Zugabe sogar unerwünschte Nebenerscheinungen hervorruft.According to the new process, such porous starting materials can also be used Find uses that: Have a rich silica content. This salary is z. B. with certain oil shale slags, 1o to 8o percent. In others too It does not occur with a silica content of around 2o to 4o percent or more Rarity. For the production of pressure-resistant stones from such materials you need: it the addition of lime, the hydraulically veri holding compounds with the silica comes in, while according to the previously known he does not and with more abundant Adding it even causes undesirable side effects.
Im nachstehenden sei als Ausführungsbeispiel die Herstellung von Mauersteinen u. dgl. aus ölschieferschlacke dargelegt. Man sortiert zunächst die Schlacke, siebt sie in mehrere Korngrößen ab und mischt die feinste Siebfeine mit Staubkalk etwa im Verhältnis ,5 : i. Alsdann setzt man. dem Gemisch Zement etwa im Verhältnis 6 : r sowie etwas gröbere Siebfeine zu und gibt uTasser im Überschuß bei, so daß sich ein dünnflüssiger Brei bildet. In diesen füllt man nun die vorher abgesiebte Schlacke in trockenem Zustande ein. Das Wasser verschwindet dabei, nahezu -augenblicklich, und es bildet sich ein erdfeuchter Beton, der in bekannter Weise durch Stampfen oder Pressen zu Mauersteinen o. dgl. verarbeitet wird, die durch nachfolgendes Abbinden die erforderliche Festigkeit und Härte annehmen. Bei dem Einwerfen der trockenen Schlacke bildet sich um jedes Korn deutlich .ein dichter Belag des Bindemittels.In the following, the production of bricks is an exemplary embodiment and the like set out from oil slate slag. First the slag is sorted and sieved it into several grain sizes and mixes the finest sieve fines with powdered lime, for example in the ratio, 5: i. Then you sit down. the cement mixture approximately in the ratio 6 : r as well as somewhat coarser sieve fines and adds uTasser in excess so that a thin one Forms porridge. In this one now fills the before sieved slag in a dry state. The water almost disappears -in an instant, and an earth-moist concrete is formed, which in the known way by ramming or pressing into bricks o. The like. Is processed by subsequent setting take on the required strength and hardness. In which Throwing in the dry slag clearly forms around each grain Coating of the binding agent.
