Appendix C - Corrosion Resistant Alloys for Reinforced Concrete
EXAMPLE CALCULATION OF CORROSION RATE FROM WEIGHT LOSS DATA
The average corrosion rate, CR, over the exposure duration was determined from before and after specimen weight measurements using the expression,
 | (3.3) |
where W is weigh loss, ρ is metal density, A is exposed rebar specimen surface area, and T is exposure time. From the density of iron (steel) and typical experimental parameters:
| W = 1.6 grams |
| ρ = 7.87·106 grams/m3, |
| A = 76·10-4 m2, and |
| T = 0.0767 years (28 days), |
