Description
Verfahren zur Herstellung beliebig geformter Baukörper. Gegenstand vorliegender Erfindung ist ein Verfahren zur Erzeugung beliebig ge formter Baukörper aus Schlacken, insbeson dere aus Hausmüll gewonnenen Schlacken und besteht darin, dass die Schlacke durch Verbrennung aller brennbaren Stoffe und Überhitzen, sowie nachfolgendes Erkalten in den Zustand der Hartsinterung gebracht und nach Wiedererwärmen mit ebenfalls heissen bituminösen Stoffen unter einem Druck bis 300 Atmosphären zusammengepresst wird.
Beifolgende Zeichnung zeigt in Fig. 1 eine Draufsicht auf einen nach dem Ver fahren hergestellten Baukörper und in Fig. 2 ein Schaubild desselben.
Die Herstellung der Baukörper wird bei spielsweise folgendermassen durchgeführt: Die hartgesinterte Schlacke wird zerklei nert und nach Korngrössen von 0-1, 1-2, 2-3 und 3-5 tnm abgesiebt, worauf An teile der genannten Körnungen in einem sol- eben Verhältnis vermischt werden, dass nach der in Fig. 1 gezeigten, stark vergrösserten Darstellung eines Steines die Hohlräume, welche die grösseren Schlackenkörper a, a', a2 zwischen sich freilassen, durch die klei neren Schlackenkörper<I>b, b',</I> b2 ausgefüllt werden, so dass nur mögliehst kleine Zwi schenräume übrig bleiben,
die insgesamt einen Hohlraum ergeben (das sogenannte Hohlraum- Minimum) der höchstens 10 Gewichtsprozente Bitumen aufnimmt. Dieses Gemisch wird sodann auf etwa 180 C erhitzt, und der erhitzten Masse werden bituminöse, möglichst hochklebfähige Stoffe hinzugefügt, die auf etwa 180 C zu erhitzen sind, und mit dem beissen Schlackengemenge vermischt werden, Praktische Versuche haben ergeben, dass der Zuschlag an Bitumen bis etws 10 Ge wichtsprozente betragen kann, je nach den Anforderungen, welcha an die Steine gestellt werden.
Alsdann erfolgt die Einfüllung der Masse in die Formen einer Presse, die die Mi schung unter einem Druck von beispielsweise 2-300 kg pro cm2 presst, womit die Bil dung eines dauernd unlösbaren Steingefüges gewährleistet wird.
Besonders vorteilhaft hat sich die Ver wendung von hartgesinterter Sehlacke aus Hausmüll erwiesen. Das Verfahren zur Her stellung solcher Schlacken ist zum Beispiel in dem schweizerischen Patent Nr. 128681 beschrieben. Diese Schlacke besitzt eine gleichmässige Zusammensetzung und grosse Dichte und hat, wie durch Versuche festge stellt wurde, eine Festigkeit von etwa 1500 kg/cm '.
Der so gewonnene, zum Beispiel nach Fig. 2 gestaltete Pressling kann, nachdem er etwa eine halbe Stunde abgekühlt ist, ohne jedwede Nachbehandlung als fertiger Stein verwendet werden.
Process for the production of structures of any shape. The subject of the present invention is a method for the production of arbitrarily shaped structures from slag, in particular slag obtained from household waste, and consists in the fact that the slag is brought into the state of hard sintering by burning all combustible substances and overheating, as well as subsequent cooling and also after reheating hot bituminous material is compressed under a pressure of up to 300 atmospheres.
The accompanying drawing shows in Fig. 1 a plan view of a structure produced according to the Ver drive and in Fig. 2 a diagram of the same.
The construction of the structure is carried out, for example, as follows: The hard-sintered slag is crushed and sieved according to grain sizes of 0-1, 1-2, 2-3 and 3-5 tnm, whereupon parts of the specified grains in such a ratio are mixed so that, according to the greatly enlarged representation of a stone shown in FIG. 1, the cavities which the larger slag bodies a, a ', a2 leave between them, through the smaller slag bodies <I> b, b', </ I > b2 must be filled in so that only the smallest possible spaces remain,
which in total result in a cavity (the so-called cavity minimum) that absorbs a maximum of 10 percent by weight of bitumen. This mixture is then heated to about 180 C, and bituminous, highly adhesive substances are added to the heated mass, which are to be heated to about 180 C and mixed with the bitter slag mixture. Practical tests have shown that the addition of bitumen up to About 10 Ge weight percent can be, depending on the requirements, which are placed on the stones.
The mass is then poured into the molds of a press that presses the mixture under a pressure of 2-300 kg per cm2, for example, which ensures the formation of a permanently insoluble stone structure.
The use of hard-sintered optical varnish from household waste has proven particularly advantageous. The process for producing such slags is described in Swiss Patent No. 128681, for example. This slag has a uniform composition and high density and has, as has been determined by tests, a strength of about 1500 kg / cm '.
The compact thus obtained, for example designed according to FIG. 2, after it has cooled for about half an hour, can be used as a finished stone without any post-treatment.
