Question
During an oedometer test on a specimen of saturated clay, the thickness of the
specimen decreased from 19.931 mm to 19.720 mm under an increment of stress
from 200 to 400 kPa which was maintained for 24 hours. The stress was then
removed from the specimen, its thickness was measured as 19.842 mm, and its
water content determined as 26.8%.
Taking Gs of the particles to be 2.7o, calculate the void ratio before and after the
application of the stress increment, and the coefficient of volume decrease (m,) for
this stress range. (Ans: e;= 0.731, e2= 0.713, m, = 0.052 m/MN)
