Abstract
This paper deals with the effectiveness of corrosion inhibitors to reduce corrosion initiation of steel reinforcements in concrete structures. Nine organic substances have been selected in previous research: 2 amines, 4 amino-acids and 3 carboxylates compounds. Laboratory tests in concrete simulating solutions and chlorides containing concrete slabs are presented and discussed, on the basis of inhibitor functional group and chlorides content. Results are also discussed taking into account the most likely mechanism of inhibition effect and the influence of inhibitors on corrosion initiation time in term of increase of critical chlorides threshold.
