Prediction of Service Life of Reinforced Concrete Structure Exposed to Chlorides

Please supply the following parameters (defaults provided) (Click here for guidance)

External chloride concentration kg/m3 concrete

Chloride conc. needed at reinforcement to start corrosion kg/m3 concrete Guidance

Reinforcement depth m

Standard deviation in reinforcement depth m

Chloride Diffusion Coefficient x10(-12) m2/s

Click here to estimate D from mix design data.

Estimation of service life is based on solution of Fick's second law for diffusion into a semi-infinite media as described elsewhere.
