A 3 m thick stratum (drained in two directions) of saturated Clay and under overburden, exhibited 90% primary consolidation in 75 days. Find the coefficient of consolidation of the clay for the pressure range. a) Take a 30 mm thick specimen, how long will it take for it to show 80% consolidation in the laboratory for a similar length of pressure, consider a two-way drain? b) If the specimen is 25 mm, time to reach 60% consolidation, with drainage in one direction?
