ASTM C1152
Full Name
ASTM C1152 – Standard Test Method for Acid-Soluble Chloride in Mortar and Concrete
Scope
ASTM C1152 provides procedures for sampling and analyzing hydraulic-cement mortar or concrete to determine the amount of acid-soluble chloride present. In most cases, the acid-soluble chloride is equivalent to the total chloride content.
The scope of ASTM C1152 includes:
- Sampling: outlines procedures for obtaining representative samples of mortar or concrete for chloride analysis.
- Sample preparation: details the steps involved in preparing the samples for analysis, including crushing, pulverizing, and acid digestion.
- Chloride determination: describes the method for determining the concentration of acid-soluble chloride in the prepared samples, typically using a titration or other analytical techniques.
- Interferences: addresses potential interferences, such as sulfides from blast-furnace slag aggregates, and outlines procedures to mitigate their effects on the results.
- Limitations: acknowledges that the test method may detect chloride that is not readily available for corrosion and that some aggregates contain chloride that is not relevant to corrosion.
Overall, ASTM C1152 aims to provide a standardized and reliable method for measuring acid-soluble chloride in mortar and concrete, which is crucial for assessing the risk of corrosion in reinforced concrete structures.
