Abstract
Inhibitory properties of three chemical products based on phosphate (Na3PO4, K2HPO4 and Na2PO3F) have been studied in synthetic concrete mediums contaminated by chlorides and then in reinforced concrete. Electrochemical measurements revealed that immersion of 7 d in 1 M K2HPO4 offered a maximum efficiency “75%”, while for Na3PO4 and Na2PO3F, 1 d of immersion in molar solution provides inhibitory efficiencies “70 and 67%”, respectively. Scanning electron microscopy tests performed on samples rinsed following the optimal duration, show that the film deposited on the surface varies for each tested product; so that the evolution of film properties is connected with electrical parameters which constituted the equivalent electrical circuit.
