 der Korngrösse der Masseteilchen stattfindet, wodurch sich die Masse setzt und   gefährliche   Hohlräume entstehen. 



   Man hat nun zwar in Vorschlag gebracht, derartige poröse Massen durch Zusatz geeigneter Bindemittel im Behälter zu einer festen kompakten Masse zu formen. Hieraus ergibt sich aber der Nachteil, dass bei unachtsamer Behandlung der Behälter eine Zerbrechung der porösen Masse und dadurch Spaltenbildung im Innern der Masse entsteht. Weiter ergibt sich aber noch der Mangel, dass derartige feste poröse Massen sich leicht besonders im oberen Teil der Behälter verstopfen, wodurch ihre   Gebrauchsfähigkeit   bedeutend herabgesetzt wird und ihre. Widerherstellung   umständliche   Arbeit erfordert. 



   Nach der Erfindung werden die geschilderten Mängel nun dadurch beseitigt, dass als Grundkörper für die poröse Masse Holzsägemehl oder Sägespäne vorgesehen sind, die zwecks Verminderung ihrer Feuergefährlichkeit und Erhöhung ihrer   Aufsaugfähigkeit   und Quellbarkeit mit Azeton oder einem anderen geeigneten Extraktionsmittel, wie z. B. Alkohol, Äther, Ketone usw., extrahiert werden. Nach der Extraktion werden die Sägespäne durch Trocknen von jeder Feuchtigkeit befreit und allein oder in Mischung mit ebenfalls vorgetrockneter Kieselguhr, Bimssteinpulver oder anderen porösen unverbrennbaren Körpern mittels   Ramm-oder   Rüttelwerkes in die Behälter gebracht. 



   Zufolge der Quellbarkeit der Sägespäne erhält die trockene festgerammte Masse nach dem Einbringen der   Lösungsflüssigkeit   im Behälter eine derartige Spannung, dass eine Lagenverschiebung bzw. 



  Veränderung   der die poröse Masse bildenden einzelnen Teilchen zueinander vollständig ausgeschlossen ist.   



   Durch geeignete Auswahl der   Korngrösse   der Sägespäne und der Zusatzmittel und deren Menge hat man es in der Hand, die Porosität der Masse in bestimmten Grenzen zu halten.

 the grain size of the mass particles takes place, whereby the mass settles and dangerous cavities arise.



   A proposal has now been made to shape such porous masses into a solid, compact mass by adding suitable binders to the container. However, this results in the disadvantage that if the container is carelessly handled, the porous mass will break and this will result in the formation of gaps in the interior of the mass. But there is also the shortcoming that such solid, porous masses easily become clogged, especially in the upper part of the container, as a result of which their usability is significantly reduced and theirs. Restoration requires cumbersome work.



   According to the invention, the shortcomings outlined are now eliminated in that wood sawdust or sawdust are provided as the base body for the porous mass, which in order to reduce their fire hazard and increase their absorbency and swellability with acetone or another suitable extractant, such as. B. alcohol, ether, ketones, etc., are extracted. After the extraction, the sawdust is freed of any moisture by drying and brought into the container alone or in a mixture with likewise predried kieselguhr, pumice stone powder or other porous, incombustible bodies by means of ramming or vibrating mechanisms.



   As a result of the swellability of the sawdust, the dry, firmly rammed mass receives such a tension after the introduction of the solution liquid in the container that a shift in position or



  Changes in the individual particles forming the porous mass to one another are completely excluded.



   By suitable selection of the grain size of the sawdust and the additives and their amount, it is in hand to keep the porosity of the mass within certain limits.
