A clay layer of thickness 10 cm and initial void ratio 0.5 undergoes settlement so that the final void ratio is 0.2. The settlement of the layer in cm is:

Under a given load a clay layer attains 30% degree of consolidation in 100 days. The time taken by the same clay layer to attain 60% degree of consolidation will be:

The natural void ratio of a saturated clay strata, 3 m thick is 0.9. The final void ratio of clay at the end of consolidation is expected to be 0.71. The total consolidation settlement of clay strata is

A clay layer of thickness 10 cm and the initial void ratio of 0.5 undergoes settlement so that the final void ratio is 0.2. The settlement of the layer (in cm) is:

When effective stress on a normally consolidated clay is increased from 25 kN/m² to 50 kN/m², settlement becomes 5 mm. If the stress is increased to 175 kN/m², settlement will increase to (assuming coefficient to volume decrease to be constant):
