1. Scope
1.1 This test method covers the determination of strength and stress-strain relationships of a cylindrical specimen of either an undisturbed or remolded noncohesive soils or sands. Specimens are isotropically consolidated and sheared in compression with drainage at a constant rate of axial deformation (strain controlled). 1.2 This test method provides for the calculation of principal stresses and axial compression by measurement of axial load and axial deformation. 1.3 This test method provides data useful in determining strength and deformation properties such as Mohr strength envelopes. Generally, three specimens are tested at different effective consolidation stresses to define a strength envelope. 1.4 The determination of strength envelopes and the development of relationships to aid in interpreting and evaluating test results are beyond the scope of this test method and must be performed by a qualified, experienced professional. 1.5 The values stated in SI units shall be regarded as the standard. The values stated in inch-pound units are approximate. 1.6 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
