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 lb/yd3 concrete

Chloride conc. needed at reinforcement to start corrosion lb/yd3 concrete Guidance

Reinforcement depth in

Standard deviation in reinforcement depth in

Chloride Diffusion Coefficient in2/yr

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