ASTM C1556 − 11a Standard Test Method for Determining the Apparent Chloride Diffusion Coefficient of Cementitious Mixtures by Bulk Diffusion

ASTM C1556 − 11a Standard Test Method for Determining the Apparent Chloride Diffusion Coefficient of Cementitious Mixtures by Bulk Diffusion

Scope

1.1 This test method covers the laboratory determination of the apparent chloride diffusion coefficient for

hardened cementitious mixtures.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

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.

ASTM C1556 − 11a Standard Test Method for Determining the Apparent Chloride Diffusion Coefficient of Cementitious Mixtures by Bulk Diffusion

Significance and Use

5.1 This test method is applicable to cementitious mixtures that have not been exposed to external chloride ions,

other than the negligible quantity of chloride ion exposure from sample preparation using potable water, prior to

the test.

5.2 The calculation procedure described in this test method is applicable only to laboratory test specimens

exposed to a sodium chloride solution as described in this test method.

This calculation procedure is not applicable to specimens exposed to chloride ions during cyclic wetting and

drying.
