Designation:D483210Standard Test Method forPreparation and Testing of Controlled Low Strength Material(CLSM)Test Cylinders1This standard is issued under the fixed designation D4832;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()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 of cylindrical test specimens ofcontrolled low strength material(CLSM)for the determinationof compressive strength.1.2 This test method covers CLSM materials that have ahigher strength than the soil but less than 8400 kPa(1200 psi).Typical strengths for most applications fall between 350 to 700kPa(50 to 100 psi).1.3 The CLSM used to make the molded specimens shall besampled after all on-site adjustments have been made to themixture proportions,including the addition of mix water andany admixtures.1.4 This test method may be used to prepare and testcylindrical specimens of other mixtures of soil and cementi-tious materials,such as self-cementing fly ashes.1.5 CLSM is also known as flowable fill,controlled densityfill,soil-cement slurry,soil-cement grout,unshrinkable fill,K-Krete,and other similar names.1.6 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.6.1 The procedures used to specify how data are collected/recorded and calculated in this standard are regarded as theindustry standard.In addition,they are representative of thesignificant digits that should generally be retained.The proce-dures used do not consider material variation,purpose forobtaining the data,special purpose studies,or any consider-ations for the users objectives;and it is common practice toincrease or reduce significant digits of reported data to becommensurate with these considerations.It is beyond the scopeof this standard to consider significant digits used in analysismethods for engineering design.1.7 The values stated in SI units are to be regarded as thestandard.The inch-pound equivalents given in brackets are,inmost cases,rationalized units and are shown for informationonly.1.8 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.See Section 7.2.Referenced Documents2.1 ASTM Standards:2C31/C31M Practice for Making and Curing Concrete TestSpecimens in the FieldC39/C39M Test Method for Compressive Strength of Cylin-drical Concrete SpecimensC125 Terminology Relating to Concrete and Concrete Ag-gregatesC192/C192M Practice for Making and Curing Concrete TestSpecimens in the LaboratoryC470/C470M Specification for Molds for Forming ConcreteTest Cylinders VerticallyC617 Practice for Capping Cylindrical Concrete SpecimensC1231/C1231M Practice for Use of Unbonded Caps inDetermination of Compressive Strength of Hardened Con-crete CylindersD653 Terminology Relating to Soil,Rock,and ContainedFluidsD3740 Practice for Minimum Requirements for AgenciesEngaged in Testing and/or Inspection of Soil and Rock asUsed in Engineering Design and ConstructionD5971 Practice for Sampling Freshly Mixed ControlledLow-Strength MaterialD6023 Test Method for Density(Unit Weight),Yield,Ce-ment Content,and Air Content(Gravimetric)of Con-trolled Low-Strength Material(CLSM)D6024 Test Method for Ball Drop on Controlled Low1This test method is under the jurisdiction ofASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.15 on Stabilization WithAdmixtures.Current edition approved Jan.15,2010.Published March 2010.Originallyapproved in 1988.Last previous edition approved in 2002 as D4832 02.DOI:10.1520/D4832-10.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Strength Material(CLSM)to Determine Suitability forLoad ApplicationD6026 Practice for Using Significant Digits in GeotechnicalDataD6103 Test Method for Flow Consistency of ControlledLow Strength Material(CLSM)3.Terminology3.1 Definitions:3.1.1 For common definitions of terms in this standard,referto Terminology C125 and D653.3.1.2 Controlled Low Strength Material(CLSM),nAmixture of soil,aggregates(sand,gravel,or both),cementitiousmaterials,potable water,and sometimes admixtures,that hard-ens into a material with a higher strength than the soil but lessthan about
