Oct 28, 2016 · Two types of grain size analyses are typically performed 1) Mechanical analysis also know as sieve analysis. Sieving is generally used for coarse-grained soils. (for particle sizes larger than 0.075 mm in diameter) 2) Hydrometer analysis ( sedimentation ) Sedimentation procedure is used for analyzing fine- grained soils.( for particle sizes smaller than 0.075 mm in diameter).
