ASTM C1152/C1152M-20

Standard Test Method for Acid-Soluble Chloride in Mortar and Concrete

SIGNIFICANCE AND USE
4.1 The amount of acid-soluble chloride in most hydraulic-cement 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.  
4.2 Sulfides are known to interfere with the determination of chloride content. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results. Treatment with hydrogen peroxide, as discussed in Test Methods C114, is used to eliminate such interference.  
4.3 There are aggregates that contain chloride that is not available for corrosion. Such chloride will be detected by the use of this method.4
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.  
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
