ASTM D6103-97

Standard Test Method for Flow Consistency of Controlled Low Strength Material (CLSM)

SCOPE
1.1 This test method covers the procedure for determination of the flow consistency of fresh Controlled Low Strength Material (CLSM). This test method applies to flowable CLSM with a maximum particle size of 19.0 mm (3/4 in.) sieve.  
1.2 The values stated in SI units are to be regarded as standard. The inch-pound equivalents are given for information only.  
1.3 CLSM is also known as flowable fill, controlled density fill, soil-cement grout, unshrinkable fill, K-Krete, and other similar names.  
1.4 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.
