This document describes a method for determining the unidirectional apparent chloride diffusion coefficient and surface concentration of specimens of hardened concrete. The test method enables the determination of the chloride penetration after a specified length of curing and length of exposure to NaCl solution.
Since resistance to chloride penetration depends on ageing which includes the effects of continual hydration and interactions with the chloride solution, then the apparent chloride diffusion coefficient also changes with age. A procedure to determine this ageing, expressed here by an ageing exponent, is included in this document and described in Annex A.
The test procedure does not apply to concrete with surface treatments such as silanes and it does not apply to concrete containing fibres (see Clause D.1).

This document specifies a method of determining the carbonation rate of a concrete, expressed in mm/va.
This document establishes a procedure where a standardized climate-controlled chamber is used and where specimens are placed on a natural exposure site protected from direct rainfall. The standardized climate-controlled chamber procedure is the reference method.
These procedures are applicable for the initial testing of concrete, including that manufactured with slowly reacting binders, provided that the ages at which the carbonation depth is measured, the number of measurements required to calculate the carbonation rate, as well as the length of exposure to CO2, are appropriately selected, as described in this document.
These procedures are not applicable for factory production control.

This document describes a method for evaluating the carbonation resistance of concrete using test conditions that accelerate carbonation. After a defined period of curing and a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide.
NOTE The test performed under reference conditions takes a minimum of 112 days comprising a minimum age of the specimen prior to curing under water of 28 days, a minimum preconditioning period of 14 days and an exposure period to increased carbon dioxide level of 70 days.
This procedure is not a method for the determination of carbonation depths in existing concrete structures.
