Test Method Title
Standard Test Method for Materials Finer than 75-µm (No. 200) Sieve in Mineral Aggregates by Washing
Description of Test
A sample of dry aggregate of known mass is washed with water to remove fines less than the No. 200 sieve. Material greater than the No. 200 sieve is dried and weighed to determine the percent less than the No. 200 particle size.
Preferred Test Sample Size
Typically 10 kg preferred, but smaller amounts required for samples with smaller maximum aggregate sizes.
Number of Test Specimens
Test Specimen Size
Typically 5 kg preferred, but smaller amounts required for samples with smaller maximum aggregate sizes.
