ASTM C566
Full Name
ASTM C566 – Standard Test Method for Total Evaporable Moisture Content of Aggregate by Drying
Scope
ASTM C566 is a standard test method used to determine the total evaporable moisture content of aggregate samples. This includes both surface moisture and moisture absorbed within the pores of the aggregate. However, it does not measure any chemically combined water present in the aggregate, as this is not considered evaporable.
Key aspects covered by ASTM C566:
- Applicability: the test method is applicable to various types of aggregates, including fine and coarse aggregates used in construction.
- Purpose: the main purpose is to quantify the total evaporable moisture content, which is crucial for adjusting the proportions of ingredients in concrete mixtures and ensuring the desired workability and strength.
- Procedure: it involves drying a representative sample of aggregate to a constant mass and calculating the percentage of moisture loss.
Overall, ASTM C566 is a fundamental test method for ensuring the quality and consistency of concrete mixtures by accurately determining the moisture content of aggregates. This helps to maintain the desired water-cement ratio, which is essential for achieving the desired properties of concrete.
