This study was carried out to identify the effective length of embedded segmented steel element with sacrificial anode exposed to non-homogeneous chloride environment against macro-cell corrosion. Four concrete specimens which consist of chloride contaminated and non-chloride contaminated concrete were evaluated. Results show that sacrificial anode can protect embedded steel in the boundary of non-homogeneous chloride environment with the effective length is about 120 mm until 200 mm from edge of the boundary.
