Description

Verfahren zur Herstellung porösen Betons. Die Erfindung bezweckt, einen porösen Zementbeton herzustellen, der sich zu verschiedenen Bauzwecken gut eignet. Es ist bekannt, solchen Beton in der Weise herzustellen, -daß man kleine Teile eines in Wasser unlöslichen, aber durch Erhitzen schmelzbaren Stoffes, z. B. von Paraffin, bei der Bereitung des Betongemisches diesem zusetzt und nach dem Abbinden des Betons wieder aus demselben ausschmilzt.Process for the production of porous concrete. The invention aims to produce a porous cement concrete that is good for various building purposes suitable. It is known to produce such concrete in such a way that one small Parts of a substance which is insoluble in water but fusible by heating, e.g. B. of paraffin, this adds in the preparation of the concrete mixture and after Setting of the concrete melts out of the same again.

Gemäß der Erfindung wird zu diesem Zwecke der Beton :der Einwirkung eines Dampfstromes, und zwar vorteilhafterweise überhitzten Dampfes ausgesetzt. Dieses Verfahren ist nicht nur leicht und rasch ohne Beschädigung des Betons ausführbar; sondern bewirkt auch eine vollständige Entfernung des zugesetzten Stoffes, indem der Dampf in die entstehenden Poren des Betons eindringt und darin zurückgebliebene Stoffteilchen verdampft und austreibt.According to the invention, concrete is used for this purpose: the action a stream of steam, advantageously exposed to superheated steam. This process is not only easy and quick to carry out without damaging the concrete; but also causes a complete removal of the added substance by the steam penetrates into the pores of the concrete and what remains there Particles of substance evaporate and expel.

Der dem Betongemisch zuzusetzende Stoff wird vorzugsweise in Form von Kügelchen von ungefähr i bis 5 mm im Durchmesser verwendet, ist aber auch in anderen Formen und Größen verwendbar. Die Stoffteilchen werden den anderen Bestandteilen des Gemisches, wie Portlandzement, Wasser, Sand üsw., zugesetzt, und zwar kann dies bei gewöhnlicher Temperatur geschehen. Nachdem der Beton gemischt und an Ort und Stelle in Formen o. dgl. gebracht ist, läßt man ihn abbinden. Nach genügendem Abbinden wird, wie erwähnt, der Beton der Einwirkung eines Dampfstromes ausgesetzt, wobei die Stoffteilchen schmelzen und ausfließen oder verdampfen und ausströmen, so daß der Beton porös wird.The substance to be added to the concrete mix is preferably in the form used by spheres approximately 1 to 5 mm in diameter, but is also used in other shapes and sizes can be used. The particulate matter becomes the other constituents of the mixture, such as Portland cement, water, sand etc., added, and this can be done done at ordinary temperature. After the concrete is mixed and in place and Place is brought into forms or the like. It is allowed to set. After sufficient setting as mentioned, the concrete is exposed to the action of a stream of steam, whereby the particles melt and flow out or evaporate and flow out so that the concrete becomes porous.

Der Beton kann dann noch mit einem Härte- und Festigungsmittel, wie z. B. mit einer Lösung von Natronwasserglas, behandelt werden. Schließlich kann die Außenfläche mit einem Zement- o. dgl. Verputz versehen werden, um ihr die nötige Festigkeit oder sonstige Eigenschaften zu verleihen. Die Betonmasse kann auch durch Metalleinlagen verstärkt werden.The concrete can then still with a hardening and strengthening agent, such as z. B. be treated with a solution of soda water glass. Finally can the outer surface with a cement o. The like. Plaster to give her the necessary To give strength or other properties. The concrete mass can also through Metal inserts are reinforced.
