要旨 |
This research aims at investigation of influence of coupled effect of limited oxygen and moisture diffusion on corrosion process of RC structures under various defined conditions quantitatively for which the previous data is limited. About 100 RC corrosion cells with different compositions and moisture exposures have been used in laboratory tests. The experiment results (half-cell potential and gravimetric mass loss) show that the diffusion of oxygen is a vital limiting factor for corrosion only when the concrete is either submerged under water or is in high relative humidity environment. |
