Carbonation vs Chloride — The Two Root Causes of Rebar Corrosion, and How to Match the Right Protection
Rebar in concrete corrodes by two fundamentally different mechanisms: carbonation (pH drop, uniform corrosion) and chloride attack (localized pitting). How to tell them apart with phenolphthalein + chloride profiling, EN 206 exposure classes, the Tuutti model, and how to match protection (cover, CP anodes, coatings) to the actual cause.
