Standard Test Method for
Preparation and Testing of Controlled Low Strength Material
(CLSM) Test Cylinders1
This standard is issued under the fixed designation D 4832; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope *
1.1 This test method covers procedures for the preparation,
curing, transporting, and testing cylindrical test specimens of
controlled low strength material (CLSM) for the determination
of compressive strength.
1.2 This test method also may be used to prepare and test
specimens of other mixtures of soil and cementitious materials,
such as self-cementing fly ashes.
1.3 CLSM is also known as flowable fill, controlled density
fill, soil-cement slurry, soil-cement grout, unshrinkable fill,
K-Krete, and other similar names.
1.4 The values stated in SI units are to be regarded as the
standard. The inch-pound equivalents are shown for information only.
1.5 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. See Section 7.
