Designation:D163300(Reapproved 2007)Standard Test Methods forCompressive Strength of Molded Soil-Cement Cylinders1This standard is issued under the fixed designation D1633;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This test method covers the determination of the com-pressive strength of soil-cement using molded cylinders as testspecimens.1.2 Two alternative procedures are provided as follows:1.2.1 Method AThis procedure uses a test specimen 4.0 in.(101.6 mm)in diameter and 4.584 in.(116.4 mm)in height.Height to diameter ratio equals 1.15.This test method made beused only on materials with 30%or less retained on the34-in.(19.0-mm)sieve.See Note 3.1.2.2 Method BThis procedure uses a test specimen 2.8 in.(71.1 mm)in diameter and 5.6 in.(142.2 mm)in height.Heightto diameter ratio equals 2.00.This test method is applicable tothose materials that pass the No.4(4.75-mm)sieve.1.3 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.4 The values stated in inch-pound units are to be regardedas standard,except as noted in 1.4.1 1.4.3.The values givenin parentheses are mathematical conversions to SI units,andare provided for information only and are not consideredstandard.1.4.1 The gravitational system of inch-pound units is usedwhen dealing with inch-pound units.In this system,the pound(lbf)represents a unit of force(weight),while the unit for massis slugs.1.4.2 The slug unit of mass is almost never used incommercial practice(density,scales,balances,etc.).Therefore,the standard unit for mass in this standard is either kilogram(kg)or gram(g),or both.Also,the equivalent inch-pound unit(slug)is not given.1.4.3 It is common practice in the engineering/constructionprofession in the United States to use concurrently pounds torepresent both a unit of mass(lbm)and of force(lbf).This usecombines two separate system of units,the absolute system andthe gravitational system.It is scientifically undesirable tocombine the use of two separate sets of inch-pound units withina single standard.As stated in 1.4.2,this standard uses thegravitational system and does not present the slug unit formass.However,the use of scales or balances recording poundsof mass(lbm)or the recording of density in lbm/ft3shall not beregarded as nonconformance with this standard.1.5 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.2.Referenced Documents2.1 ASTM Standards:2C42/C42M Test Method for Obtaining and Testing DrilledCores and Sawed Beams of ConcreteD559 Test Methods for Wetting and Drying CompactedSoil-Cement Mixtures(Withdrawn 2012)3D560 Test Methods for Freezing and Thawing CompactedSoil-Cement Mixtures(Withdrawn 2012)3D653 Terminology Relating to Soil,Rock,and ContainedFluidsD1632 Practice for Making and Curing Soil-Cement Com-pression and Flexure Test Specimens in the LaboratoryD2216 Test Methods for Laboratory Determination of Water(Moisture)Content of Soil and Rock by MassD3740 Practice for Minimum Requirements for AgenciesEngaged in Testing and/or Inspection of Soil and Rock asUsed in Engineering Design and ConstructionD4753 Guide for Evaluating,Selecting,and Specifying Bal-ances and Standard Masses for Use in Soil,Rock,andConstruction Materials TestingD6026 Practice for Using Significant Digits in GeotechnicalDataE4 Practices for Force Verification of Testing Machines1This 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 Feb.1,2007.Published March 2007.Originallyapproved in 1959.Last previous edition approved in 2000 as D1633 00.DOI:10.1520/D1633-00R07.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.*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 3.Terminology3.1 For definitions of terms used in this test method,refer toTerminology D653.4.Significance and Use4.1 MethodAmakes use of the same compaction equipmentand molds commonly available in soil laboratories and used foro
