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.

3D LiDAR Scanning + Cathodic Protection: Find the 'Symptom' Before Failure, Stop the 'Cause' at the Rebar

Why modern structural inspection pairs two things: 3D LiDAR scanning that measures settlement, cracking and spalling down to millimeter level, then Cathodic Protection that stops the rebar corrosion that is the real cause. The scan → diagnose → protect → monitor lifecycle for bridges, buildings and railways — with the realistic accuracy (cm/mm) achievable, no overclaiming.
