Description

Verfahren zur Herstellung poröser Baustoffe Bei Herstellung von porösem Beton, sogenanntem Gasbeton, mittels gasentwickelnder Stoffe und hvdratulischer Bindemittel hat sich Aluminium als Gasentwickler dadurch verwendbar erwiesen, <laß es mit den alkalischen Bestandteilen bzw. Zusätzen des Bindemittels Aluminiumhydrat und Wasserstoffgas bildet. Fs ist hierbei für dieHomogenität und Festigkeit des porösen Betons von großer Bedeutung, daß die Anfangsmischung in einem geeigneten Verhältnis zu der Abbindungszeit des Materials steht, damit die Gasentwicklung bei beginnender Abbindung und während des Erhärtens nicht sprengend wirkt. Um dies zu erreichen, zerkleinerte man bisher die gasentwickelnden Stoffe sehr fein, was jedoch die Cbelstände herbeigeführt hat, daß teils die erzeugten Gasblasen sehr klein und von unzweckmäßiger Größenverteilung wurden, teils d aß die Zerkleinerungskosten, insbesondere bei Verwendung von reinem Aluminium als Gaserzeuger, sich sehr hoch stellen.Process for the production of porous building materials In the production of porous building materials Concrete, so-called aerated concrete, by means of gas-evolving substances and hvdratulischer As a binder, aluminum has proven to be useful as a gas generator it with the alkaline components or additives of the binder aluminum hydrate and forms hydrogen gas. Fs is here for the homogeneity and strength of the porous concrete of great importance that the initial mix in a suitable Relation to the setting time of the material stands so that the gas development with beginning to set and does not have a disruptive effect during hardening. To do this reach, so far the gas-evolving substances have been comminuted very finely, which, however the Cbelstands has brought about that some of the gas bubbles generated are very small and of inexpedient size distribution, partly because of the comminution costs, especially when using pure aluminum as a gas generator, it is very high place.

Die vorliegende Erfindung betrifft nun eine Verbesserung des genannten Verfahrens dadurch, daß statt reinen Aluminiums Altuniniumlegierungen als Gaserzeuger verwendet «erden, was folgende Vorteile herbeiführt: Die Legierungen können so gewählt werden, (laß ihre Gasentwicklung zu dem für die betreffende Gasbetonmischung geeignetsten Zeitpunkt und mit der zweckmäßigsten Intensität eintritt, ohne daß man die Legierungen besonders fein zu pulverisieren ])raucht, und daß demnach eine zweckmäßige Größenverteilung der Blasen erreicht wird.The present invention now relates to an improvement on the foregoing Process in that, instead of pure aluminum, aluminum alloys are used as gas generators used «, which brings about the following advantages: The alloys can be selected (let their gas evolution be the most suitable for the gas concrete mixture in question Time and with the most appropriate intensity occurs without the alloys especially finely pulverized]) smokes, and that accordingly an appropriate size distribution the bubbles is reached.

Als geeignete Legierungen sind zu nennen: A1",Fe, A1.Ca, AI,Zn3, AI"Mg., A1"Cu oder Magnaliuni. Die Zerkleinerungskosten können beträchtlich herabgedrückt werden, da man die Zerkleinerung nicht soweit zti treiben braucht und weil die betreffenden Legierungen infolge ihrer Sprödigkeit viel geringere Arbeit bei der Zerkleinerung erfordern, «-elche außerdem nicht bei höherer Temperatur oder in einer Wasserstoffatmosphäre zu geschehen braucht.Suitable alloys are: A1 ", Fe, A1.Ca, Al, Zn3, Al" Mg., A1 "Cu or Magnaliuni. The grinding cost can be reduced considerably because you do not need to drive the comminution as far as zti and because the relevant Alloys, due to their brittleness, do much less work in crushing require, «-which also do not take place at a higher temperature or in a hydrogen atmosphere needs to happen.

Das teure Aluminiuminetall kann mit weniger teuren Metallen gestreckt, und es können auch unreine Aluminiumprodukte verwendet «-erden.The expensive aluminum metal can be stretched with less expensive metals, and impure aluminum products can also be used.

Aluminiumlegierungen haben sich gut bewährt, wo Zement, Gips, Schwefelkalk, Kalk und Gemische von Kalle und kieselhaltige Stoffe, wie Sand, Zement, Hochofen- und Flamrnofenschlacke, Koksasche und Lösche, als Bindemittel benutzt werden. Als Zuschlagsstoffe haben sich Sand, Ton, Hochofen-und Flammofenschlacke, Schwefelkiesrückstände, Lösche, Koks-, Torf- und Schieferasche, Ziegelsteinschlag, Sägespäne, Dolomit, Kalkstein, Kalzit, Kalktuff und Kalkmergel als zweckm:ißig erwiesen.Aluminum alloys have proven themselves well where cement, gypsum, sulfur lime, Lime and mixtures of potash and siliceous substances such as sand, cement, blast furnace and furnace slag, coke ash and quench, can be used as binders. as Aggregates have sand, clay, blast furnace and furnace slag, pebble residues, Extinguish, coke, peat and slate ash, broken bricks, sawdust, dolomite, limestone, Calcite, limestone tuff and limestone marl proved to be useful.
