Description

Verfahren zur Herstellung von Zellbeton o. dgl. Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von porösen Kunststeinen (Zellbeton, Gasbeton, Luftzement usw.). Dieser wird in bekannter Weise z. B. gewonnen, wenn man einer Mischung, die als Grundstoff Kalk- oder Zementmörtel enthält, ein feines Metallpulver, wie Aluminium oder Zink, zusetzt. Unter diesen Bedingungen verursacht das Metall eine Entwicklung von Gasblasen, die das zu einer festen Masse erstarrende Produkt porös machen, ihm große Leichtigkeit, Schalldichtigkeit und besonders ausgeprägte Wärmeisolierfähigkeit verleihen. Es ist auch bekannt, derartige Massen unter: Überdruck erstarren zu lassen.Method for producing cellular concrete or the like. The present invention relates to a process for the production of porous artificial stones (cellular concrete, aerated concrete, Air cement, etc.). This is in a known manner z. B. won if one Mixture containing lime mortar or cement mortar as a base material, a fine metal powder, like aluminum or zinc. Under these conditions the metal causes a development of gas bubbles that solidify the product into a solid mass make it porous, giving it great lightness, soundproofing and particularly pronounced Give thermal insulation ability. It is also known to use such masses under: Overpressure to freeze.

Die Erfindung ist besonders für Kalkmassen mit hohem Kieselsäurezuschlag anwendbar, die mit Dampf behandelt werden müssen.The invention is particularly useful for lime masses with a high silica addition applicable, which must be treated with steam.

Die Erfindung besteht in einem besonderen Verfahren zur Erzeugung des Überdrucks, bei welchem die Gasblasen bis zum endgültigen Festwerden der Masse in ihr festgehalten werden sollen.The invention consists in a particular method of production the overpressure at which the gas bubbles until the mass finally solidifies should be held in it.

Zu diesem Zweck füllt man erfindungsgemäß die Masse, die die gasbildende Substanz enthält, teilweise in eine Form ein, die vollkommen geschlossen wird, sobald die Masse sich soweit aufgebläht hat, daß sie die Form völlig ausfüllt. Wenn es sich um eine Kieselsäure-Kalkmischung, also eine Kalksandsteinmischung handelt, so setzt man die Form dann in einen Autoklaven, wobei der gesamte Inhalt in bekannter Weise mit Dampf von 8 bis zo Kilo Überdruck erhitzt wird. Durch diese Arbeitsweise läßt sich, wie festgestellt wurde, eine beträchtliche Verbesserung im Verhältnis zu gleichartigen Produkten, die in offener Form erhitzt worden sind, erzielen. Der Widerstand gegen Bruch ist: erheblich gewachsen, die Gasblasen sind besser und bedeutend feiner in der festen Masse verteilt.For this purpose, according to the invention, the mass that forms the gas is filled Contains substance, partly in a form that is completely closed once the mass has inflated so far that it completely fills the shape. If it it is a silica-lime mixture, i.e. a sand-lime brick mixture, so one then puts the mold in an autoclave, with the entire contents in known Way is heated with steam from 8 to ten kilograms overpressure. Through this way of working It has been found that there is a considerable improvement in the ratio to similar products that have been heated in an open mold. Of the Resistance to rupture: has grown considerably, the gas bubbles are better and more significant finely distributed in the solid mass.

Selbstverständlich ist die Erfindung keineswegs auf Produkte aus Beton oder Kalksandstein beschränkt.Of course, the invention is by no means applicable to products made of concrete or sand-lime brick.
