  • Unconfined Compression (UC) Test - Civil Engineering

    The undrained shear strength (su) of clays is commonly determined from an unconfined compression test. The undrained shear strength (su) of a cohesive soil is equal to one half the unconfined compressive strength (qu) when the soil is under the f = 0 condition (f = the angle of internal friction).

  • Unconfined Compressive Strength Test of Rock

    This test method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting without grinding, and neoprene caps are used on the specimen ends. Unconfined Compressive Strength Test Procedure Check the ability of the spherical seat ...

  • UNCONFINED COMPRESSION TEST -

    data are used to determine the strength of the soil specimen and the stress-strain characteristics. Finally, the sample is oven dried to determine its water content. The maximum load per unit area is defined as the unconfined compressive strength, qu. In the unconfined compression test, we assume that no pore water is lost from the

    of Soil Analysis (7). The compressive stresses ap­ plied were from 1 Kg/cm' to 5 Kg, cm'. The mois­ ture contents of the tested samples were determined 90 after the experiments. Soil cohesion: The force necessary to cause a metal-wedge to penetrate the soil mass was de­ termnied with the apparatus devised by YAMANAKA (10).

    unconfined compressive strength of 250 psi (1724 kpa) at 7 days. This paper presents the soil-cement mix design, field-laboratory procedure and results. The construction sequences and the basic design example of the soil-cement mix are also given in this paper. Lastly, the results of the soil-cement improvements are shown. 1. INTRODUCTION

    The compressive strength increased with an increase in dry density in each of the materials. NC exhibited the highest increase in compressive strength followed by CS-I and then by CS-II. The compressive strength increased from 220 kPa at a dry density of 1.2 g/cm3 to 4000 kPa at 1.5 g/cm3.
