In a consideration test, an increase of 100 KN/m² in the vertical pressure applied to a saturated clay sample initially 2.5cm thick. The thickness of the sample reduced to 2.46cm after 24 hours. The sample was then relieved of pressure and allowed to take up water. The final thickness was 2.465cm and the moisture content was 30%. Assuming that the sample was saturated throughout the test, calculate the following:- i) The initial void ratio. (take G-2,68) ii) The void ratio after consolidation, iii) The void ratio after expansion. iv) The coefficient of compressibility.
