To syudy the change of prtential in the mortar-embedded precorroded rebar, a half cell method was adapted. The rebar was corroded by the salt spray and then the rebar embedded in the mortar. A saturated copper sulfate feference electrode was used. The corrosion potential of the rebar in the mortar specimen cured in air was increased, whereas that of the rebar cured in water was decreased with aging. The corrosion potential of the rebar in the mortar was decreased with corroded time by the salt spray. As the mortar thickness covered the rebar was increased, the corrosion potential of the rebar in the mortar was increased.
