    Abstract

    The consolidation behavior of laboratory prepared “young” specimens of two clay soils, kaolin and Dundas soil, was examined using conventional consolidation tests. The specimens were prepared under either isotropic or K0 stress conditions. A fixed-ring type consolidometer was used for the tests. A 24-h loading time increment with a load increment ratio of 1.0 was used.

    Test results indicate that the consolidation behavior of both soils was influenced by the past loading history and the test loading conditions. The soils were able to remember the past maximum stress.

    Based on the test results, normalized e-σ‵v relationships are suggested for the two soils.
