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.

UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch ge kennzeichnet, dass die hartgesinterte Schlacke durch Zerkleinerung gekörnt und die ge körnte lasse sortiert und so gemischt wird. PATENT CLAIM: Process for the production of any shaped building structure from slag, in particular slag obtained from household waste, as it is characterized in that the slag is hard-sintered by burning all combustible substances and overheating, as well as being reheated after cooling and with constricted, also hot bituminous substances is compressed under a pressure of up to 300 atmospheres. SUBSTANTIAL CLAIM: Method according to patent claim, characterized in that the hard-sintered slag is granulated by crushing and the granulated lass is sorted and so mixed. dass nur Zwischenräume übrig bleiben, die insgesamt einen Hohlraum ergeben, der höch stens 10 Cewicht@prozeriteBitumen aufnimmt, worauf das Gemisch erhitzt und mit den bituminösen Stoffen zusammengepresst wird. that only gaps remain, which in total result in a cavity that can hold a maximum of 10 Cewicht @ prozerite bitumen, whereupon the mixture is heated and pressed together with the bituminous substances.
