1、Designation:D559/D559M15Standard Test Methods forWetting and Drying Compacted Soil-Cement Mixtures1This standard is issued under the fixed designation D559/D559M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revisi
2、on.A number in parentheses indicates the year of last reapproval.A superscript 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 These test methods cover procedures for determi

4、ribed in Test Methods D558.1.2 Two test methods,depending on soil gradation,arecovered for preparation of material for molding specimens andfor molding specimens as follows:SectionsTest Method A,using soil material passing a 4.75-mm No.4sieve.This method shall be used when 100%of the soil samplepass
5、es the 4.75-mm No.4 sieve.7Test Method B,using soil material passing a 19.0 mm 0.75-in.sieve.This method shall be used when part of the soil sample isretained on the 4.75-mm No.4 sieve.This test method may be used only on materials with 30%orless retained on the 19.0-mm 0.75-in.sieve.81.3 All observ
6、ed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026,unless superseded by this test method.1.3.1 The procedures used to specify how data are collected/recorded and calculated in the standard are regarded as theindustry standard.In a
7、ddition,they are representative of thesignificant digits that generally should 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 sign
8、ificant digits of reported data to becommensurate with these considerations.It is beyond the scopeof these test methods to consider significant digits used inanalysis methods for engineering data.1.4 UnitsThe values stated in either SI units or inch-pound units presented in brackets are to be regard
9、ed sepa-rately as standard.The values stated in each system shall beused independently of the other.Combining values from thetwo systems may result in non-conformance with the standard.Sieve size is identified by its standard designation in Specifi-cation E11.The alternative designation given in par
10、entheses isfor information only and does not represent a different standardsieve size.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.The rationalized slug uni
11、t is not given,unless dynamic(F=ma)calculations are involved.1.4.2 It is common practice in the engineering/constructionprofession to use pounds to represent both a unit of mass(lbm)and of force(lbf).This implicitly combines two separatesystems of units;that is,the absolute system and the gravita-ti
12、onal system.It is scientifically undesirable to combine the useof two separate sets of inch-pound units within a singlestandard.As stated,this standard includes the gravitationalsystem of inch-pound units and does not use/present the slugunit for mass.However,the use of balances or scales recordingp
13、ounds of mass(lbm)or recording density in lbm/ft3shall notbe regarded 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
14、health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C150 Specification for Portland CementC595 Specification for Blended Hydraulic CementsD558 Test Methods for Moisture-Density(Unit Weight)Relations of Soil-Cement Mixture
