• A stratum of clay 2 m thick will get consolidated 80% in 10 years. For the 80% consolidation of 8 m thick stratum of the same clay, the time required is
• A normally consolidated clay settled 10 mm when effective stress was increased from 100 kN/m² to 200 kN/m². If the effective stress is further increased from 200 kN/m² to 400 kN/m², then the settlement of the same clay is
• The maximum value of effective stress in the past divided by the present value is defined as over consolidation ratio (OCR). The O.C.R. of an over consolidated clay is
• When the seepage pressure becomes equal to the pressure due to submerged weight of a soil, the effective pressure is reduced to zero and the soil particles have a tendency to move up in the direction of flow. This phenomenon is generally known
• The ratio of the undrained strength in the undrained state to the undrained strength, at the same water content, in the remoulded state, is called the sensivity of the clay. Its value for quick clays is
• If drainage is permitted throughout the test, during the application of both normal, and shear stresses so that full consolidation occurs and no excess pore pressure is set up at any stage of the test, is known as
• For testing a saturated clay for shear strength, the test recommended, is
• The clay mineral with the largest swelling and shrinkage characteristics is
• A structure is erected on an impervious clay whose thickness is 12 m. Drainage is possible both at upper and lower surfaces. Coefficient of consolidation is 0.015 cm2 per minute. For attaining 50% consolidation with a time factor 0.20, the number of days required
