Fines Content Grain Size
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.
Typically 5 kg preferred, but smaller amounts required for samples with smaller maximum aggregate sizes.
