Relationship between coulomb and migration coefficient of chloride ions for concrete in a steady-state chloride migration test

摘要

A steady-state chloride migration test with a constant electrical potential drop of 15 V was conducted with a saturated 100 mm diameter × 50 mm long concrete specimen. The migration coefficient of chloride ions for concrete was calculated using the constant flux on the basis of the Nernst-Planck equation. Electrical current was simultaneously monitored throughout the entire period of the migration test.
