Products and systems for the protection and repair of concrete structures. Test methods. Determination of carbonation depth in hardened concrete by the phenolphthalein method Ingestion-build-111333 the sample being introduced into1 Scope The phenolphthalein test method is intended to measure the depth of the carbonated layer near the surface of hardened concrete. It is not suitable for concrete made with calcium aluminate cement. It may be used on site or in the laboratory, on test specimens or on cores or fragments removed from hardened concrete structures.
