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.

Question

A building is constructed on the ground surface
beneath which, there is a 2 m thick saturated
clay layer sandwiched between two highly previous
layers. The building starts settling with time. If
the average coefficient of consolidation of clay is
2.5 x104 cm2/s, in how many days will the building
reach half of its final settlement? TEo = 0.197
