Potential corrosion of the steel rebars within retaining wall
Potential corrosion of the steel rebars within retaining wall
(OP)
Is it any way to estimate the effective life span of steel reinforcement in a wet environment?
Here is the problem:
The rebars are grouted and located approx 3" or less from the face of the wall.
Where the seepage through retaining wall is occurring, the seepage is through hairline cracks and through grout between blocks. The worst case scenario is to assume that the rebars are in constantly wet condition.
Soil samples of on-site soils adjacent to the wall indicate:
- pH of 8.01
- soluble sulfate content range of 210 to 270 ppm
- chloride content range of 1029 to 1437 ppm
- minimum emectrical resistivity range of 4452 to 5936 ohm-cm.
Thanks a lot

From your description of blocks and grout I'm not sure what the construction is. Can you be more specific?
