The concentration and valence of other ionic species in the pore fluid also influence the rate of chloride diffusion, atsm therefore, the apparent diffusion coefficient as determined by this test procedure.
ASTM C1556: “Apparent Chloride Diffusion Coefficient of Cementitious Mixtures”
Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard. 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.
Print and complete the following order form.
Instructions The sample specimens may be cores, cylinders, or cubes. Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. The diffusion of ionic species in concrete occurs within the fluid-filled pores, cracks and void spaces.
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. 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.
Use The apparent chloride diffusion coefficient is asm to estimate chloride penetration into cementitious mixtures that are in a saturated condition.

Order Form 2 Email complete form to contact listed below. The apparent diffusion coefficient determined by this method includes bound chloride, so proper use of the apparent chloride diffusion coefficient to predict xstm ingress requires consideration of chloride binding.
Results Produced The apparent chloride diffusion coefficient.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided adtm part of the 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.
