Testing hardened concrete - Part 11: Determination of the chloride resistance of concrete, unidirectional diffusion
Abstract
This European Standard is a method for determining the unidirectional apparent chloride diffusion coefficient and surface concentration of conditioned 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 the ageing, including the effects of continual hydration and interactions with the chloride solution, then the apparent diffusion coefficient will also change with age. A procedure to determine this ageing, expressed here by an ageing exponent, is included in the standard and described in an annex. The test procedure does not apply to concrete with surface treatments such as silanes and it may not apply to concrete containing fibres
