Results Produced The apparent chloride diffusion coefficient. This calculation procedure is not applicable to specimens exposed to chloride ions during cyclic wetting and drying. ASTM C states that each sample consists of at least two 2 specimens.

Use The apparent chloride diffusion coefficient is used to estimate chloride penetration into cementitious mixtures that are in a saturated condition.

No other units of measurement are included in this standard. The apparent diffusion coefficient determined by this method includes bound chloride, so proper use of the apparent chloride diffusion coefficient to predict chloride ingress requires consideration of chloride binding.

ASTM C1556: “Apparent Chloride Diffusion Coefficient of Cementitious Mixtures”

x1556 Client must specify the exposure age, water cementitious ratio and if a pozzolan or slag has been used as it is required to modify the depth intervals as specified in ASTM C’s Recommended Depth Interval Table. The rate of change of the apparent diffusion coefficient for cementitious mixtures containing pozzolans or blast-furnace slag is typically different than that for mixtures containing only portland cement.

Instructions The sample specimens may be cores, cylinders, or cubes. Link to Active This link will always route to the current Active version of the standard.

The concentration and valence of other ionic species in the pore fluid also influence the rate of chloride diffusion, and therefore, the apparent diffusion coefficient as determined by this test procedure. Privacy Policy Sensors Sitemap. Order Form 2 Email complete form to contact listed below. The calculation procedure described in C is only applicable to specimens exposed to a sodium chloride solution as described in C, not to specimens exposed to chloride ions during cyclic wetting and drying.

Therefore, apparent diffusion coefficients obtained at early ages may not be representative of performance in service.
