ICS Code (Physical properties of soils): | 13.080.20 |
significance And Use:
The term shrinkage limit, expressed as a moisture content in percent, represents the amount of water required just to fill all of the voids of a given cohesive soil at its minimum void ratio... View More
scope:
1.1 This test method covers the procedure for determining the shrinkage limit of soils.
1.2 The data obtained using this test method may also be used to calculate shrinkage ratio, volumetric shrinkage, and linear shrinkage.
1.3 This test method is applicable only for cohesive soils.
1.4 Since this test method is performed only on that portion of a soil which passes the No. 40 (425-μm) sieve, the relative consistency of this portion of the soil to the properties of the sample as a whole must be considered when using these procedures to evaluate the properties of a soil.
1.5 The shrinkage limit along with the liquid limit and plastic limit of soils are often collectively referred to as the Atterberg limits in recognition of their formation by Swedish soil scientist, A. Atterberg. These limits distinguish the boundaries of the several consistency states of cohesive soils.
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.7 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. For specific safety hazards, see Section 7, Note 2, and Note X1.1.
