Abstract EN
The corrosion risk of internal chloride and external chloride from three different exposure conditions was evaluated.
The initiation of corrosion was detected by monitoring the galvanic current between cathode metal and embedded steel.
The chloride threshold was determined by measuring the corrosion rate of steel by the polarization technique for internal chloride and the chloride profiling test for external chloride.
As the result, the initiation of corrosion was accelerated with a cyclic wet/dry condition, compared to the totally wet condition.
In addition, it was found that an increase of the drying ratio in the exposure condition resulted in an increase of corrosion rate after initiation.
The threshold level of external chloride ranged from 0.2 to 0.3% weight by cement and internal chloride shows higher range, equated to 1.59–3.10%.
Based on these data, the chloride penetration with exposure condition was predicted to determine the service life of reinforced concrete structure.
