    Verfahren zur Verhinderung   der Verdunstung des Anmachwassers aus   Zementbeton.   



   Die vorliegende Erfindung bezieht sich auf das Abbinden von   Zementmater1alien,   bei welchen während der Abbindeperiode die   Veidampfung   des   Anmaehwassers   aus dem Beton durch eine wasser-   undurchlässige   Haut, die auf die Oberfläche des Materials aufgebracht wird, verhindert wird und hat ein verbessertes Verfahren dieser Art zum Gegenstande. 



  Demgemäss besteht das Verfahren der vorliegenden Erfindung darin, dass Zementmaterial, nach- dem es fertiggestellt ist, d. h., nachdem es geglättet oder gegebenenfalls abgekehrt ist und bevor es ab- gebunden hat, d. h. also, bevor es die Belastung durch ein grösseres Gewicht, wie z. B. das eines sich auf ; Lm bewegenden Mannes ohne Beschädigung aushält, mit einer Bitumenemulsion von wässeriger äusserer
Phase behandelt wird. wodurch eine   wasserundurchlässige   Haut auf der Oberfläche des Betonmaterials gebildet wird. 



   Zur   praktischen Ausführung   des Verfahrens der Anmeldung wird eine Bitumenemulsion mit wässeriger äusserer Phase auf die   Oberfläche   von nassem, frisch verlegtem Beton, z. B. mittels eines Zer- stäubers aufgebracht. Eine derartige Emulsion besitzt die Eigenschaft, bald nachdem sie der Luft aus- gesetzt wurde, infolge des Verdampfens des Wassers zu zerfallen, so dass ein undurchlässiges, anhaftendes
Häutchen entsteht. 



   Die bituminöse Emulsion kann aufgetragen werden, sobald die Oberfläche fertiggestellt ist oder es kann erst das Oberflächenwasser abtrocknen gelassen werden.

    Method to prevent evaporation of the mixing water from cement concrete.



   The present invention relates to the setting of cement materials, in which during the setting period the evaporation of the coarse water from the concrete is prevented by a water-impermeable skin which is applied to the surface of the material, and has as its object an improved method of this type .



  Accordingly, the method of the present invention is that, after the cement material is completed, i. i.e. after it has been smoothed or, if necessary, turned away and before it has set, d. H. so, before the burden of a greater weight, such as B. the one up; Lm moving man withstands without damage, with a bitumen emulsion of watery exterior
Phase is treated. whereby a water impermeable skin is formed on the surface of the concrete material.



   For the practical implementation of the process of the application, a bitumen emulsion with an aqueous outer phase is applied to the surface of wet, freshly laid concrete, e.g. B. applied by means of an atomizer. Such an emulsion has the property, soon after it has been exposed to the air, to disintegrate as a result of the evaporation of the water, so that an impermeable, adherent
Skin emerges.



   The bituminous emulsion can be applied as soon as the surface is finished or the surface water can first be allowed to dry off.
