Table 4 Ratio of the chloride concentration in a circular RC cross-section and the chloride concentration of the plane RC element \( C/C_{slab} \) estimated at depth \( \rho_{1} = 8\,\rm{cm} \) from the external surface.
\( C/C_{slab} \) | t = 1 year | t = 5 years | t = 10 years | t = 20 years | t = 50 years |
|---|---|---|---|---|---|
R = 20 cm | – | 1,295 | 1,298 | 1,304 | 1,323 |
R = 30 cm | – | 1,169 | 1,170 | 1,172 | 1,176 |
R = 50 cm | – | 1,091 | 1,092 | 1,092 | 1,093 |
R = 100 cm | – | 1,043 | 1,043 | 1,043 | 1,043 |
R = 150 cm | – | 1,028 | 1,028 | 1,028 | 1,028 |
