Beschreibung
Zusammenfassung:	The invention is directed to a corrosion inhibition system for reinforced concrete, to reinforced concrete comprising said corrosion inhibition system, and to a process for preparing said reinforced concrete, and to the use of said reinforced concrete. In accordance with the invention, a corrosion inhibition system for concrete reinforced with a corrosion sensitive reinforcement is provided, which system comprises layered double hydroxide intercalated with a compound represented by the following formula (I): YRCOO- (I) and/or protonated forms thereof, wherein Y is NH 2 or COO- R is an optionally substituted aromatic, aliphatic, or cycloaliphatic moiety having 5-18 carbon atoms.
