SSC SSC JE Civil 2025 Mock Test Series (Paper 1 & Paper 2) Soil Mechanics and Foundation Engineering Consolidation
In a consolidation test the void ratio is found to be 0.98 under the effective pressure of 194 kN/m2, later the void ratio reduced to 0.89 when the pressure is increased to 400 kN/m2. The coefficient of compressibility is:
1
2.39 x 10-2 m2/kN
2
4.36 x 10-4 m2/kN
3
6.38 x 10-5 m2/kN
4
8.36 x 10-3 m2 /kN
