Question: A 3 m thick clay layer beneath building is over - lain by a permeable stratum and is underlain by an impervious rock. The coefficient

A 3m thick clay layer beneath building is over-lain by a permeable stratum and is underlain by an impervious rock. The coefficient of consolidation of the clay was found to be 0.025cm2min. The final expected settlement for the layer is 8cm.
(i) How much time will it take for 80% of total settlement to take place?
(ii) Determine the time required for a settlement of 2.5cm.
(iii) What will be settlement in 6 months?
