ASTM C1556: “Apparent Chloride Diffusion Coefficient of Cementitious Mixtures”
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. If you need more info or have any questions, please note the Lab ID number and contact us at: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
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. Order Form 2 Email x1556 form to contact listed below.

The diffusion of ionic species in concrete occurs within the fluid-filled asstm, cracks and void spaces.

Historical Version s – view previous versions of standard. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ASTM C states that each sample consists of at least two 2 specimens. Instructions The sample specimens may be cores, cylinders, or cubes. Results Produced The apparent chloride diffusion coefficient.
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.
No other units of measurement are included in this standard. Therefore, apparent diffusion coefficients obtained at early ages may not be representative of performance in service.
