Description
<Desc/Clms Page number 1>
Verfahren zur Herstellung von Beton mit geringem spezifischen Gewichte.
Bekannt ist die Erzeugung eines leichten Betons unter Verwendung des Bimssteines als Zuschlagsstoff, doch-besitzt derselbe einerseits keine ausreichende Festigkeit für tragende Konstruktionen und stellt sich andrerseits wegen der hohen Transportkosten für Gegenden, welche vom Fundorte weit entfernt sind, zu teuer.
Vorliegende Erfindung bezweckt die Herstellung eines leichten Betons unter Verwendung eines künstlich erzeugten porösen Zuschlagsstoffes aus gebranntem Ton. Poröse Steine werden zum Zwecke besserer Wärmeisolierung bekanntlich erzeugt, indem zum angemachten Ton verbrennbare Bestandteile zugemengt werden. Es folgt dann das Brennen der Steine, welche an jenen Stellen, wo sich der verbrennbare ZusÅatz befand, Poren besitzen. Für die Betonbereitung kommen aber diese Erzeugnisse wegen ihrer geringen Festigkeit und der von der Schotterform abweichenden, meist ziegelförmigen Gestalt nicht in Frage. Um einen für die Betonberditung geeigneten leichten Zuschlagsstoff zu gewinnen, soll erfindungsgemäss Ton
EMI1.1
dann nachträglich durch Zerkleinern auf die gewünschte Korngrösse gebracht werden.
Die Erzeugung des leichten Zuschlagsstoffes kann aber auch in der Art erfolgen, dass nach Beimengung des verbrennbaren Materials die Teilung des Gemenges in Schotter und Sandkörner sogleich vorgenommen wird und nachträglich das Brennen bis über die Sintergrenze erfolgt. Das Erzeugnis, welches ausser geringem spezifischem Gewichte noch erhebliche Festigkeit besitzt, wird dann in bekannter Weise zur Betonherstellung verwendet.

Process for the production of concrete with low specific gravity.
The production of light concrete using pumice stone as an aggregate is known, but on the one hand it does not have sufficient strength for load-bearing structures and on the other hand it is too expensive because of the high transport costs for areas far away from the site.
The present invention aims to produce a lightweight concrete using an artificially produced porous aggregate from burnt clay. Porous stones are known to be produced for the purpose of better thermal insulation by adding combustible components to the clay. This is followed by the burning of the stones, which have pores in those places where the combustible additive was located. For concrete preparation, however, these products are out of the question because of their low strength and the mostly brick-shaped shape, which deviates from the ballast shape. In order to obtain a light aggregate that is suitable for concrete overburden, clay according to the invention
EMI1.1
then subsequently brought to the required grain size by crushing.
The light aggregate can also be produced in such a way that, after the combustible material has been added, the mixture is immediately divided into gravel and grains of sand and subsequently burning to beyond the sintering limit. The product, which in addition to its low specific weight still has considerable strength, is then used in a known manner to produce concrete.
