USCS Description Cohesion (kPa) Friction angle (°) Soil

Cohesion is the component of shear strength of a rock or soil that is independent of interparticle friction. In soils, true cohesion is caused by following: 1. Electrostatic forces in stiff overconsolidated clays (which may be lost through weathering) 2. Cementing by Fe2O3, Ca CO3, Na Cl, etc. WebMay 29, 2024 · Cohesive soil is hard to break up when dry, and exhibits significant cohesion when submerged.
