Abstract:
The chloride threshold va lue ( CTV) is one of crucial param e ters for determ ining the serv ice life of re inforced concre te structure exposed to ch lo rides. According ly, it has becom e an emphas is of research on the durab ility o f re inforced concrete struc ture. In th is pape r, the research m ethods o f CTV including m ass loss, hal-f cell po tentia,l macroce l,l linea r po larization, e lectrochem ica l im pendence spectro scopy and other e lectro chem ica l m ethods have been rev iew ed. Especia lly, the m echanism s, som e im po rtant features and ex istent issues in eva luation m ethods are introduced. The research ind icates that due to the d ifferences o f mechan ism and standard o f identify ing the co rros ion initiation, the CTVs obta ined by the var ious research me thods m ay be different. So, the different research m ethodsm ay have contr ibu ted to the scatte r o f CTV reported in the perv ious lite ratures.
