Description
Verfahren zur Herstellung eines dichten Oberflächenbetons, insbesondere für Wasserbauten, wie Talsperren u. dgl. Um einen an der Außenfläche dichten Beton zu erhalten, wird u. a. das bekannte Verfahren zum Entwässern des Betons durch Unterdruck, .die sogenannte Vakuumschalung, verwandt.Process for the production of a dense surface concrete, in particular for hydraulic structures such as dams and the like to obtain is, inter alia. the well-known method of draining concrete using negative pressure, .the so-called vacuum shuttering, related.
Durch das Verfahren gemäß der Erfindung soll auf anderem Wege die Entwässerung des Betons erreicht und; damit ein dichter Oberflächenbeton erzielt werden. Zu diesem Zweck werden die bekannten Elektro-Osmose-Vorgänge herangezogen. Wie umfangreiche bereits durchgeführte Versuche erwiesen haben, wird durch die neuartige Anwendung der Elektro-Osmose-Vorgänge auf den frischen Beton eine dichte, wetterfeste Betonaußenschicht erzielt, wie sie vor allem für Wasserhauten, besonders Talsperren, gefordert werden muß. Zur Erreichung dieser Elektro-Osmose-Vorgänge im Beton werden in einigem Abstand von der Betonaußenfläche Elektroden aus Stahl oder anderem Metall, eventuell gleichzeitig als Bewehrung sowieso erforderlich, einbetoniert bzw. in Hohlräumen angeordnet, « älirend die Außenschalung mit Kupferelektroden versehen wird. Durch das Anschließen der in dem frisch eingebrachten Beton eingebauten Elektroden an den elektrischen Strom erfolgt eine Entwässerung des in der Verdichtung stehenden frischen Betons nach außen zur Schalung, von wo das entzogene Wasser abgeführt wird. Mit der Entwässerung des frischen Betons werden für den dichteren Beton günstige chemische und mechanische Vorgänge verursacht und weitere Hohlräume geschaffen, die durch die Verdichtung des Betons mittels Rüttler, möglichst Hochfrequenzrüttler, geschlossen werden. Aber auch die mit dem Entzug des Wassers durch Verlagerung und Verschlämmung auftretende dichtende Wirkung, gleich der bei der Vakuumschalung, wirkt sich aus.By the method according to the invention in other ways Drainage of concrete achieved and; so that a dense surface concrete is achieved will. The known electro-osmosis processes are used for this purpose. As extensive tests that have already been carried out have shown, the new Application of the electro-osmosis processes to the fresh concrete a dense, weatherproof Concrete outer layer achieved, as it is especially for water structures, especially dams, must be required. In order to achieve these electro-osmosis processes in concrete At some distance from the outer surface of the concrete, electrodes made of steel or other metal, possibly required at the same time as reinforcement anyway, concreted in or in Arranged cavities, provided the outer formwork with copper electrodes will. By connecting the electrodes built into the freshly poured concrete to the electric current there is a drainage of what is in the process of compression fresh concrete to the outside to the formwork, from where the extracted water is drained. With the drainage of the fresh concrete become favorable for the denser concrete causes chemical and mechanical processes and creates additional cavities, caused by the compaction of the concrete by means of vibrators, if possible high-frequency vibrators, closed will. But also those with the withdrawal of water through displacement and silting up Occurring sealing effect, the same as with vacuum shuttering, has an effect.
