Phạm vi áp dụng / Scope of standard

This method covers the procedures for determining acid-soluble chloride ions in concrete and concrete mix ingredients.

The age of concrete, mortar, or hydrated portland cement at the time of sampling will have an effect on the acid-soluble chloride ion content. Therefore, unless early age studies are desired, it is recommended that the material be well cured and at least 28 days of age before sampling.

This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns associated with its use.
