During a laboratory consolidation test, the time and dial gauge readings obtained from an increase of pressure on the specimen from 50 kN/m? to 100 kN/m? are given here. Dial gauge reading (10 cm) Dial gauge reading (10 cm) Time (min) Time (min) 3975 16 4572 0.1 4082 30 4737 0.25 4102 60 4923 0.5 4128 120 5080 1 4166 240 5207 2 4224 480 5283 4 4298 960 5334 8 4420 1440 5364 Using the logarithm-of-time method, determine c. The average height of the specimen during consolidation was 2.24 cm, and it was drained at the top and bottom.
