Study Notes
Clay Properties
- Type: Sedimentary, clastic, argillaceous
- Strength: Older, more lithified, and unweathered clays have higher strength. Younger clays have properties transitional to low-strength soils.
- Unconfined Compressive Strength (UCS): 1–20 MPa
- Sensitivity and Bearing Pressure (SBP): 0.1–1 MPa
Clay Foundation Considerations
- Foundations: Weak material with low, variable strength largely due to water content.
- Potential Issues: Prone to slow creep and plastic deformation. High potential for compaction leading to high and differential settlement under structural loads.
