Verbesserung der Frost-Tausalz-Beständigkeit von Betonkonstruktionen |
摘要 |
<p>To improve the frost/de-icing salt resistance of concrete constructions, in particular the road surfacings and runways of airports, which had already been produced with air-entraining agents, a solution of the following composition is applied to the concrete surface which is to be protected: Silica calculated as SiO2 30-32 mol Alkali metal ions " Na<+1> 23-24.3 " C1-C3-alcohol " ethanol 2- 2.1 " Carbonate " CO3<-2> 1.6- 2.1 " Water " at least 400 " The quantity applied preferably amounts to 100-300 g/m<2> of concrete area.</p> |
