In a consolidation test the following data was obtained: Void ratio of the soil = 0.75; Specific gravity of the soil = 2.62; Compression Index = 0.1. The thickness of the compressible soil is 3 m. The increase in pressure at the center of the layer is 60 kN/m2. The preconsolidation pressure is 50 kN/m2. If the coefficient of consolidation is 2 × 10^–7 m2/s, determine the time in days for 90% consolidation. Assume one-way drainage. a. 333 b. 442 c. 346 d. 426
