Description

Verfahren zum Beschleunigen des Abbindens und Erhärtens von Beton Die Erfindung betrifft ein Verfahren zum Beschleunigen des Abbindens und Erhärtens von insbesondere Flüssigkeit aufsaugendem Beton durch mehrere Dampfbehandlungen.Process for accelerating the setting and hardening of concrete The invention relates to a method for accelerating setting and hardening of concrete which absorbs liquids in particular by means of several steam treatments.

Es ist leine bekannte Erscheinung, daß Beton trotz Behandlung mit Wasserdampf durch die beim Abbinden und Erhärten auftretende Eigenwärme austrocknet. Infolgedessen wird besonders bei porösem Beton nur eine unvollkommene Erhärtung erzielt. Um dies zu verhindern, wird erfindungsgemäß vorgeschlagen, eine Zwischentränkungdes zum Teil durch Dampfbehandlung vorgehärteten Betonformlings mit Wasserglas vorzunehmen.It is a well-known phenomenon that concrete, despite being treated with Water vapor dries out due to the inherent heat generated during setting and hardening. As a result, especially in the case of porous concrete, the hardening is imperfect achieved. In order to prevent this, it is proposed according to the invention that an intermediate impregnation of the partly by steam treatment of pre-hardened concrete moldings with water glass.

Da bekanntlich Wasserglaslösungen das Lösungswasser :sehr schwer abgeben, wird durch diese Tränkung die unerwünschte Verdunstung des Wassers bei :einer weiteren Dampfbehandlung des Formlings wirksam unterbunden.Since water glass solutions are known to give the water of solution: very difficult to release, This impregnation prevents the undesired evaporation of the water in: another Effectively suppressed steam treatment of the molding.

Die Anwendung des Erfindungsgedankens erfolgt beispielsweise derart, daß der durch Dampfbehandlung zum. Teil abgebundene Betonformling mit einer Wasserglaslösung getränkt und hierauf einer weiteren Dampfbehandlung bis zur vollkommenen Erhärtung ausgesetzt wird. Nötigenfalls kann diese abwechselnde Behandlung, soweit das vorteilhaft erscheint, beliebig wiederholt werden.The idea of the invention is applied, for example, in such a way that that the by steam treatment to. Partly set concrete molding with a water glass solution soaked and then a further steam treatment until it has completely hardened is exposed. If necessary, this alternating treatment can be used, as far as that is advantageous appears, can be repeated as required.

Ein nach diesem Verfahren behandelter Beton weist nach Beendigung der Wärmebehandlung erheblich größere Festigkeiten auf, als das sonst der Fall ist.A concrete treated according to this method shows after completion the heat treatment has significantly greater strengths than is otherwise the case.

Insbesondere wird durch -dieses Verfahren die Beschleunigung der Abbindung und Erhärtung durch Wärmebehandlung auch bei porösem Beton möglich.In particular, this process accelerates the setting process and hardening through heat treatment is also possible with porous concrete.
