Part 1 Determination of water content. We will measure this with the unconfined compression test which is an unconsolidated undrained UU or Q-type test where the lateral confining pressure is equal to zero atmospheric pressure. In this test the saturated soil specimen is first consolidated by an all-around chamber fluid pressure σ 3 which results in drainage.
