Consolidation test evaluates which soil property?

Consolidation test evaluates which soil property?

• A. Permeability
• B. Settlement potential
• C. Shear strength
• D. Compaction behavior

Answer: (B)

Consolidation tests focus on how a soil decreases in volume over time when a sustained load is applied, as water is squeezed out of the pore spaces. This process directly governs how much a foundation or soil fill will settle in the long term. By measuring vertical settlement under controlled drainage, you obtain the soil’s compressibility and rate of consolidation, which are used to predict settlement potential for design. This is different from permeability (which looks at fluid flow through soil), shear strength (which concerns resistance to sliding under shear), or compaction behavior (which is about densification under energy input). So the test is best for evaluating settlement potential.
