ASTM D4832/D4832M-23

Standard Test Method for Preparation and Testing of Controlled Low Strength Material (CLSM) Cylindrical Test Specimens

SIGNIFICANCE AND USE
5.1 This test method provides standardized requirements for the preparation, curing, transporting and testing of test specimens of CLSM under field conditions by replicating a “field cure” of the material.  
5.1.1 If the specimens are field cured, as stipulated herein, the resulting compressive strength test data may be used for the following purposes:
5.1.1.1 Acceptance testing for specified strength,
5.1.1.2 Checking the adequacy of mixture proportions for strength,
5.1.1.3 Quality control,
5.1.1.4 Determining if the material can be put in service,
5.1.1.5 Adequacy of curing.  
5.2 Compressive strength testing is performed to assist in the design of the mix and to serve as a quality control technique during construction. Mix design is typically based on 28-day strengths and construction control tests performed 7 days after placement. The compressive strength(s) and other test age(s) will vary according to the requirements for the end product. Additional information on the use and history of CLSM is contained in Appendix X1.  
5.3 This test is one of a series of quality control tests that can be performed on CLSM during construction to monitor compliance with specification requirements. The other tests that can be used during construction control of CLSM are Practice D5971/D5971M and Test Methods D6023, D6024/D6024M, and D6103/D6103M.  
5.4 There are many other combinations of soil, cement, fly ash (cementitious or not), admixtures, water or other materials that could be tested using this method. The mixtures will vary depending on the intended use, availability of materials, and placement requirements.
Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are c...
SCOPE
1.1 This test method covers procedures for the preparation, curing, transporting and testing of cylindrical test specimens of controlled low strength material (CLSM) for the determination of compressive strength.  
1.2 This test method covers CLSM materials that have a higher strength than the soil but less than 8400 kPa [1200 psi]. Typical strengths for most applications fall between 350 to 700 kPa [50 to 100 psi].  
1.3 The CLSM used to make the molded specimens shall be sampled after all on-site adjustments have been made to the mixture proportions, including the addition of mix water and any admixtures.  
1.4 This test method may be used to prepare and test cylindrical specimens of other mixtures of soil and cementitious materials, such as self-cementing fly ashes.  
1.5 CLSM is also known as flowable fill, controlled density fill, soil-cement slurry, soil-cement grout, unshrinkable fill, and other similar names.  
1.6 Units—The values stated in SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.6.1 The gravitational system of inch-pound units is used when dealing with inch-pound units. In the system, the pound (lbf) represents a unit of force (weight), while the units for mass is slugs. The slug unit is not given, unless dynamic (F = ma) calculations are involved.  
1.7 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard.  
1.7.1 For purposes of comparing, a measured or calculated value(s) with specified limits, the measured or calculated value(s) shall be rounded to the nearest decimal or significant digits in the specified limits.  
1.7.2 The procedures us...
