Corrosion.of embedded rebars is a classical deterioration.mechan.sm of rein.orced con.rete structures exposed to chloride en.iron.en.s. Such en.iron.en.s can.be attributed to the presen.e of seawater, deicin. or sea-salts, which have high con.en.ration. of chloride ion. Chloride in.ress in.o con.rete, essen.ial for in.ucin. rebar corrosion. is a complex in.eraction.between.man. physical an. chemical processes. The curren. study proposes two chloride in.ress parameter models for fly ash con.rete, n.mely： 1） surface chloride con.en. un.er tidal exposure con.ition. an. 2） chloride bin.in.. First, in.on.isten.ies in.surface chloride con.en. an. chloride bin.in. models reported in.literature, due to them n.t bein. in.lin. with past research studies, are poin.ed out. Secon.ly, to avoid such in.on.isten.ies, surface chloride con.en. an. chloride bin.in. models for fly ash con.rete are proposed based upon.the experimen.al work don. by other researchers. It is observed that, proposed models are simple, con.isten. an. in.lin. with past research studies reported in.literature.
