  • 8. STRENGTH OF SOILS AND ROCKS

    For the uniaxial or unconfined compressive strength test a right circular cylinder of the material is compressed between the platens of a testing machine as illustrated in Fig. 8.1. The compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area.

Three joint conditions were considered for evaluating the unconfined compressive strength using indirect tensile strength (joint orientation, joint roughness and number of joints).

  • Unconfined Compressive Strength (UCS)

    The unconfined compressive strength (q u) is the load per unit area at which the cylindrical specimen of a cohesive soil falls in compression. Note: If the unit axial compression force per unit area has not reached a maximum value up to 20 percent, axial strain, shall be considered the value obtained at 20 percent axial strain.

  • What is the difference between crushing strength and ...

    Answer (1 of 4): Crushing is a local failure of a material, usually over a small area and despite the fact that the area around it is confined and not readily able to dilate or fail in shear. Compressive strength is measured by the vertical force applied to an unconfined cylinder. The failure mec...

According to the ASTM standard, the unconfined compressive strength (q u) is defined as the compressive stress at which an unconfined cylindrical specimen of soil will fail in a simple compression test. In addition, in this test method, the unconfined compressive strength is taken

  • UNCONFINED COMPRESSION TEST - cyut.edu.tw

    unconfined compression test led to a significant underestimation of the strength of the soil. In fact, because the unconfined compression test does not provide confinement for the soil, and because of the effects of sampling disturbance, strengths measured in the unconfined compression test are usually a lower bound of the actual strength.

  • Unconfined compression test for determining shear strength

    26-09-2011 · Unconfined compression test. The main difference between Unconfined compression test and triaxil compression test is that in this test the confining cell pressure is kept zero during the test, in fact it is a special case of triaxial test. Due to which without applying any lateral pressure like a concrete crushing test the cylindrical soil sample is crushed to failure.
