The effectiveness of sacrificial anode to protect embedded steel in cracked concrete under different curing conditions; air curing, immersed in a 3% NaCl solution and dry/wet cyclic is presented here. Water-to-cement ratio of 0.4 and pre-crack widths varied from 0.1 to 0.4 mm were studied. Reinforced concrete prism on 150x150x500 mm in sizes with pre-cracks under flexural load was used in this study. The result showed that sacrificial anode was effective to protect the embedded steel in cracked concrete. Also crack widths significantly influence towards corrosion rate.
