Introduction In the fields of geotechnical engineering and construction material testing, understanding how soil behaves when it gets wet is not just a technical detail—it is a safety requirement. Expansive soils (often called "smectite clays" or "shrink-swell soils") can cause upward pressure on foundations, while collapsible soils can lead to sudden settlement. High-plasticity clays (CH) may require up to 14

A: Only for collapse testing (Method C). Swell testing is irrelevant for non-cohesive, granular soils because they lack clay minerals.
