A one-dimensional consolidation test was performed on a sample, 0.75-inch high, taken from a field clay layer. During the test, drainage was allowed at the upper and lower boundaries. It took the lab sample 15 minutes to reach 50% consolidation. If the clay layer in the field has the same drainage condition as the lab sample, calculate how many days it will require the 10 feet clay layer to achieve 50% and 90% consolidation.

Consolidation parameters

Consolidation is the process of expulsion of pore water present in the voids of soil solids under the pressure of the applied load. This is a quick process in the case of coarse-grained soils since the permeability is high due to the presence of more voids, while it is a slow and gradual process in the case of clayey soil as the permeability of clay is less. An example of consolidation is the settlement of soil under a building due to the load coming from the building.
