Description

Verfahren zur Herstellung eines Beton-Kies-Ersatzes Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Beton-Kies-Ersatzes, bei dem kleine Teile eines organischen oder anorganischen Grundstoffes, etwa Holz, Braunkohle, Kokosschale, Schilf, Bambus, Hanfstengel oder Kunststoffabfall mit einem filmartigen Überzug aus heißem Bitumen oder Teer ummantelt werden.Method of making a concrete-gravel replacement The invention relates to a process for the production of a concrete-gravel replacement in which small parts of an organic or inorganic base material, such as wood, lignite, Coconut husk, reeds, bamboo, hemp stalks or plastic waste with a film-like Coating made of hot bitumen or tar.

Es ist bekannt, poröse organische oder anorganische Stoffe zuerst mit heißflüssigem Bitumen zu umhüllen, mit Mineralmehl abzupudern und mit hydraulischen Bindemitteln, zusammen mit Bitumendispersion, einzubinden. Nach diesem Verfahren hergestellte Formkörper sind dadurch in ihrer Lagerfähigkeit beschränkt, daß im Laufe der Zeit der auf ihrer Oberfläche haftende Mineralpuder von Bitumen umhüllt wird, wodurch ein Zusammenbacken eintritt.It is known to first use porous organic or inorganic materials to be covered with hot liquid bitumen, powdered with mineral flour and with hydraulic To incorporate binders together with bitumen dispersion. According to this procedure produced moldings are limited in their shelf life that im Over time, the mineral powder adhering to its surface is encased in bitumen causing caking.

Ferner ist es bekannt, Bauelemente aus schwach angefeuchteten vegetabilischen Körperchen, wie Sägemehl, Korkschrot, Gerberlohe u. dgl. in Mischapparaten mit geringen Mengen Bindemitteln, wie Zement oder Kalk, innig zu mischen, bis der Bindemittelstaub auf den feuchten Füllstoffteilchen einen Überzug bildet, worauf nach Zufügung größerer Mengen Bindemittel die Weiterverarbeitung im selben Arbeitsgang erfolgt.It is also known to use components made from slightly moistened vegetable matter Bodies such as sawdust, cork grist, tannery and the like in mixers with low Mix quantities of binders, such as cement or lime, intimately until the binder dust forms a coating on the moist filler particles, followed by the addition of larger ones Quantities of binding agent that are further processed in the same operation.

Zur Herstellung rasch trocknender oder die Feuchtigkeit abstoßender Elemente können an Stelle des Wassers zum Anfeuchten der vegetabilischen Körper Lösungen verwendet werden, die härtend oder wasserabstoßend wirken, wie Chlorkalzium, Wasserglas, Öl- oder Bitumenemulsion od. dgl.For the production of rapidly drying or moisture-repellent elements, instead of water for moistening the vegetable bodies, solutions can be used that have a hardening or water-repellent effect, such as calcium chloride, water glass, oil or bitumen emulsion or the like.

Bei dem vorbekannten Verfahren soll der jeweils verwendete organische oder anorganische Grundstoff, nachdem er mit Bitumen oder Bitumenemulsion wasserdicht gemacht worden ist, als Zuschlagstoff in Mischungen zur Herstellung von Bauelementen verwendet werden.In the previously known method, the particular organic or inorganic base material after being waterproof with bitumen or bitumen emulsion has been made as an aggregate in mixtures for the production of building elements be used.

Aufgabe der Erfindung ist es demgegenüber, einen fertigen, losen Zuschlagstoff, der als Beton-Kies-Ersatz verwendet werden kann, als Halbfabrikat herzustellen, das als Schüttgut in Säcken verpackt werden kann und später beispielsweise zur Herstellung von Wandisolierputz, Estrichen oder Bauelementen verwendet wird, so daß seine Verarbeitung also nicht an eine Erzeugungsstätte für Bauelemente gebunden ist. Die nach dem vorbekannten Verfahren hergestellten Produkte müssen hingegen gleich nach ihrer Herstellung an Ort und Stelle zu Bauelementen verarbeitet werden.The object of the invention, on the other hand, is to provide a finished, loose aggregate, which can be used as a concrete-gravel substitute, to manufacture as a semi-finished product, which can be packed in sacks as bulk goods and later, for example, for production of wall insulating plaster, screeds or building elements is used, so that its processing is therefore not tied to a production site for components. The one after the previously known Process-manufactured products, on the other hand, must come on immediately after their manufacture Processed into components on the spot.

Überdies soll ein erfindungsgemäß herzustellender Beton-Kies-Ersatz möglichst feuerbeständig sein. Zur Lösung dieser Aufgabe ist das eingangs genannte Verfahren dadurch gekennzeichnet, daß die noch in heißem Zustand befindlichen, ummantelten Grundstoffteile voll mit Zementstaub bestreut werden. Der Zementstaub bindet noch aus dem Grundstoff oder aus dem heißen Bitumen oder dem Teer austretenden Wasserdampf ab und bildet einen versteinerten Überzug auf den mit Bitumen oder Teer ummantelten Grundstoffteilen.In addition, a concrete-gravel substitute to be produced according to the invention is intended be as fire-resistant as possible. To solve this problem is what was mentioned at the beginning A method characterized in that the still in the hot state, jacketed Basic material parts are fully sprinkled with cement dust. The cement dust still binds water vapor escaping from the raw material or from the hot bitumen or tar and forms a petrified coating on the bitumen or tar coated Basic parts.

Der erfindungsgemäß hergestellte Beton-Kies-Ersatz ist natürlichem Steinkies durch sein geringes Gewicht überlegen und ermöglicht die Herstellung von sehr leichten Bauelementen. Auch ist seine Warmleitfähigkeit geringer als die von Steinkies, so daß bei seiner Verarbeitung dem jeweils verwendeten Bindemittel die in diesem enthaltene Wärme nicht so rasch entzogen wird. Es ergibt sich eine raschere Abbindezeit, die gerade für die Herstellung von Schnellbau- und Betonelementen von Vorteil ist.The concrete-gravel substitute produced according to the invention is natural Due to its low weight, stone gravel is superior and enables the production of very light components. Its thermal conductivity is also lower than that of Stone gravel, so that the binder used in each case during its processing the heat contained in this is not withdrawn so quickly. There is a faster one Setting time, which is especially important for the production of quick-assembly and concrete elements from Advantage is.

Ferner ist der erfindungsgemäß hergestellte Beton-Kies-Ersatz schüttfähig und von praktisch unbegrenzter Lagerfähigkeit.Furthermore, the concrete-gravel substitute produced according to the invention is pourable and of practically unlimited shelf life.

Zur Prüfung der Feuerbeständigkeit von Formsteinen, die unter Verwendung eines erfindungsgemäßen Beton-Kies-Ersatzes hergestellt sind, wurden Hohlsteine unter Verwendung eines solchen Materials erzeugt, wobei als Grundstoff Holzkorn verwendet wurde.For testing the fire resistance of shaped bricks that are made using a concrete-gravel replacement according to the invention are produced Hollow stones produced using such a material, with wood grain as the base material was used.

Aus diesen Formsteinen wurde eine Wand errichtet und der Hohlraum in den Steinen mit Beton gefüllt. Die Prüfung erfolgte nach DIN 4102.A wall and the cavity were built from these shaped stones in the stones filled with concrete. The test was carried out in accordance with DIN 4102.

Die Prüfwand zeigte während des ganzen Brandversuches ausreichende Widerstandsfähigkeit gegen die Einwirkung des Feuers und verhinderte wirksam den Durchgang von Feuer und Rauch. Sie erfüllte die amtlichen Anforderungen an feuerbeständige Bauteile. Die Druckfestigkeit von dem dem Brandversuch ausgesetzten Probewürfel zeigte keinen nennenswerten Abfall.The test wall showed sufficient during the entire fire test Resistance to the action of fire and effectively prevented the Passage of fire and smoke. It met the official requirements for fire-resistant Components. The compressive strength of the test cube exposed to the fire test showed no significant drop.

In anderen Versuchen ergab sich, daß die Wasseraufnahmefähigkeit von Bausteinen, die mittels des genannten Beton-Kies-Ersatzes hergestellt waren, bedeutend geringer ist als die Wasseraufnahmefähigkeit von Bausteinen, die unter Verwendung von Materialien, wie sie zum eingangs genannten Stand der Technik gehören, hergestellt wurden.In other experiments it was found that the water absorbency of Building blocks that were manufactured using the concrete-gravel substitute mentioned above were significant is less than the water absorption capacity of building blocks that are made using of materials as they belong to the state of the art mentioned at the beginning became.
