Question

The equation given by Skempton for compression index for a remoulded sample is ___________

(a) Cc=0.009(wL-10%)

(b) Cc=0.007(wL-10%)

(c) Cc=0.007(wL-20%)

(d) Cc=0.007(wL-30%)

The question was asked in exam.

I need to ask this question from Consolidation Process in portion One Dimensional Consolidation of Geotechnical Engineering I

Answer 1

Right option is (b) Cc=0.007(wL-10%)

Easiest explanation: Skempton conducted consolidation tests on a number of clays from different parts of the world and gave the following expression for the compression index for remoulded sample,

Cc=0.007(wL-10%)

Where Cc=compression index

wL=liquid limit.
