Silt particle size lies between that of clay (less than .002 mm.) and sand (.05 to 2 mm.) and differs from these materials in the following ways: Texture – Dry silt feels smooth, with a floury texture. A clod of dried silt will easily crumble and break down into a powder when pressed between ...
WebUse lower values for elastic silt, and clayey or silty sands and gravel. Deduct up to 20% for dry soils. Cohesive Soil: Unconfined Compressive Strength (Qu) Undrained Shear Strength (Su) The standard practice is to determine shear strength of cohesive soils in the field based on measurements with torvane, pocket penetrometer, or vane shear.
