A raft footing is to be constructed on a 7.5 m thick clay layer which lies between two sand layers. In order to predict the time rate of settlement of the building, a 2.5 cm thick undisturbed sample of the soil was tested in the laboratory under double drainage condition. The sample was found to have undergone 50% consolidation in 12.5 minutes. Determine the time required for 50% settlement of the building in days.
