ASTM C1152/C1152M − 04 Reapproved 2012 1 Standard Test Method for Acid-Soluble Chloride in Mortar and Concrete

Scope
1.1 This test method2 provides procedures for the sampling and analysis of hydraulic-cement mortar or concrete for chloride that is acid soluble under the conditions of test.

In most cases, acid-soluble chloride is equivalent to total chloride. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Some values have only SI units because the inch-pound equivalents are not used in practice.

NOTE 1—Sieve size is identified by its standard designation in Specification E11.

The alternative designation in parentheses is for information only and does not represent a different standard sieve size.

1.3 The text of this standard references notes and footnotes that provide explanatory information.

These notes and footnotes shall not be considered as requirements of this standard.

Significance and Use
3.1 The amount of acid-soluble chloride in most hydrauliccement systems is equal to the total amount of chloride in the system.

However, some organic substances that may be introduced into mortar or concrete contain chloride that is initially acid-insoluble that can eventually ionize and thus become acid-soluble or water-soluble after a period of exposure in the very alkaline cement system.
