  • Unconfined compression test | ec7p2

    Unconfined compression test Requirements (1) The unconfined compression test should be carried out on specimens of soil of sufficiently low permeability to maintain undrained conditions during the test. (2) Delays between trimming and testing should be avoided to prevent change of water content of specimens.

  • Confined compressive strength analysis can improve PDC bit ...

    A rock strength analysis program, through intensive log analysis, can quantify rock hardness in terms of confined compressive strength to identify intervals suited for drilling with polycrystalline diamond compact (PDC) bits. Additionally, knowing the confined compressive strength helps determine the optimum PDC bit for the intervals.
