Carbonation depth measurement test, used to determine whether moisture has reached the depth of the reinforcing bars and hence corrosion may be occurring, uses pH indicators to spray on fresh fractured concrete surfaces and change the colour in the concrete zones with different pH.

A clear liquid turns pink in contact with the alkaline (non-carbonated) concrete and remains colourless in contact with carbonated concrete. The colour change usually indicates an abrupt transition between pH.

This testing method allows to perform durability diagnosis and life service prognostic relative to the carbonation deterioration process of concrete structures.
