Instructions The sample specimens may be cores, cylinders, or cubes.
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 asrm or blast-furnace slag is typically different than that for mixtures containing only portland cement.
Results Produced The apparent chloride diffusion coefficient. Historical Version s – view previous versions of 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.
ASTM C Apparent Chloride Diffusion Coefficient | CTLGroup
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 astn wetting and drying. The diffusion of ionic species in concrete occurs within the fluid-filled pores, cracks and void spaces. Link to Active This link will always route to the current Active version of the standard.

Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. No other units of measurement are included in this standard. This calculation procedure c1565 not applicable to specimens exposed to chloride ions during cyclic wetting and drying.
Print and complete the following order form.
C15556 C states that each sample consists of at least two 2 specimens. Therefore, apparent diffusion coefficients obtained at early ages may not be representative of performance in service.
