Scope. 1.1 This test method covers the determination of the unconfined compressive strength of cohesive soil in the undisturbed, remolded, or compacted condition, using strain-controlled application of the axial load.
The guidelines for unconfined compressive testing follow the ASTM standard test method. Specifically, ASTM D 2166 is the standard for testing the unconfined compressive strength of cohesive soil. ASTM C39 is the industry standard for testing the compressive strength of concrete. Users must establish proper safety and health practices . 1.3.2 The procedures used to specify how data are collected/recorded or calculated in the standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained.

Google Scholar Tiwari B, Ajmera B (2011a) New correlation equations for compression index of remolded clays. .Gilson's analog or digital component sets completely outfit any manufacturer’s load frame for testing to ASTM/AASHTO standards. Individual components are also available separately. . Results of the soil unconfined compression test are calculated using axial strain, average cross-sectional area, and compressive stress values. Axial strain, ε1:
5.1 In this test method, the compressive strength of a soil is determined in terms of the total stress, therefore, the resulting strength depends on the pressure developed in the pore fluid during loading. In this test method, fluid flow is not permitted from or into the soil specimen as the load is applied, therefore the resulting pore pressure, and hence strength, differs from . 1.1 This test method covers procedures for preparing, curing, and testing laboratory-compacted specimens of soil-lime and other lime-treated materials (Note 1) for determining unconfined compressive strength.testing of soil, Part 7: Unconfined compression test .

ASTM D7012-14 Standard test method for compressive strength and elastic moduli of intact rock core specimens
This test method provides for the measurement of the total stresses applied to the specimen, that is, the stresses are not corrected for pore-water pressure. Note 1—The determination of the unconfined compressive strength of cohesive soils is covered by Test Method D 2166. Note 2ASTM D2166 Full Name. ASTM D2166 – Standard Test Method for Unconfined Compressive Strength of Cohesive Soil. Scope. ASTM D2166 is a standard test method used to determine the unconfined compressive strength (UCS) of cohesive soils. This test is essential for evaluating the bearing capacity of soils, particularly those used in foundations and embankments. 5.1 Care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materials. Values obtained will depend on the size and shape of the specimen, batching, mixing procedures, the methods of sampling, molding, .Standard Test Method for Unconfined Compressive Strength of Cohesive Soil 1.1 This test method covers the determination of the unconfined compressive strength of cohesive soil in the intact, remolded, or reconstituted condition, .
