The time required for a 50% consolidation of a 25mm thick layer drained both sides is 2 min 20 seconds. • How long (days) will it take for a 3m thick clay layer of the same clay in the field under the same pressure increment to reach 50% consolidation? In the field, there is a rock layer at the bottom of the clay • How long in days will it take to reach 30% consolidation? • The predicted primary settlement for the lab specimen is 0.064mm. What is the average degree of consolidation when the settlement reached 0.02mm?
