This study was carried out to observe the service life of the galvanic sacrificial anode to protect steel bar from corrosion in concrete. Current acceleration method was used by adjusting the current demand 10 times higher than initial current of anode. Results show that by increasing the current demand by 10 times, it makes the service life of anode reduced significantly after 70 days of exposure. It means the higher current delivery function of anode, the service life of anode become shorter. Current acceleration method is effective to investigate the service life of anode in short time.
