ASTM C1524
Full Name
ASTM C1524 – Standard Test Method for Water-Extractable Chloride in Aggregate (Soxhlet Method)
Scope
ASTM C1524 outlines the procedures for sampling and analyzing aggregate to determine the amount of water-extractable chloride using a Soxhlet extractor. This method is typically employed when significantly high chloride content has been found in aggregates, concrete, or mortars.
The scope of ASTM C1524 includes:
- Sampling: it provides guidelines for obtaining representative samples of aggregate for chloride analysis.
- Extraction: it details the procedure for extracting water-soluble chlorides from the aggregate using a Soxhlet extractor.
- Analysis: it describes the method for determining the concentration of water-extractable chloride in the extract, usually by titration or other analytical techniques.
Key points to note:
- This test method is specifically for determining water-extractable chloride, not total chloride content.
- The Soxhlet extraction method is used when high chloride levels are suspected.
- The results of this test can help assess the potential for chloride-induced corrosion of embedded metals in concrete.
