ASTM C1556: “Apparent Chloride Diffusion Coefficient of Cementitious Mixtures”
Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. 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. This calculation procedure is not applicable to specimens exposed to chloride ions during cyclic wetting and drying. 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.
Results Produced The apparent chloride diffusion coefficient. Instructions The sample specimens may be cores, cylinders, or cubes.
Therefore, apparent diffusion coefficients obtained at early ages may not be representative of performance in service.
Use The apparent chloride diffusion coefficient is used to estimate chloride penetration into cementitious mixtures that are in a saturated condition. The rate of change of the apparent diffusion coefficient for cementitious mixtures containing pozzolans or blast-furnace slag is typically different than atsm for mixtures containing only portland cement. The apparent diffusion coefficient determined by this method includes bound chloride, so proper use of the apparent chloride astk coefficient to predict chloride ingress requires consideration of chloride binding.

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. Link to Active This link will always route to the current Active version of the standard.
The diffusion of ionic species in concrete occurs within the fluid-filled pores, cracks and void spaces. Print and complete the following order form. ASTM C states that each sample consists of at least two 2 specimens.

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.
