3、nationof the flow consistency of fresh Controlled Low StrengthMaterial(CLSM).This test method applies to flowable CLSMwith a maximum particle size of 19.0 mm 34in.or less,or tothe portion of CLSM that passes a 19.0 mm 34in.sieve.1.2 The CLSM used to make the molded specimens shall besampled after al
4、l on-site adjustments have been made to themixture proportions,including the addition of mix water andany admixtures.1.3 All observed 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values shall conform to theguidelines for significant digits and rounding established inPractice D6026 unless superseded by this test method.1.3.1 The
5、method used to specify how data are collected,calculated,or recorded in this standard is not directly related tothe accuracy to which the data can be applied in design or otheruses,or both.How one applies the results obtained using thisstandard is beyond its scope.1.4 UnitsThe values stated in eithe
6、r SI units or inch-pound units are to be regarded separately as standard.Thevalues 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 noncon-formance with the standard.1.4.1 The gravita
7、tional 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 unit is not given,unless dynamic(F=ma)calculations are involved.1.4.2 It is common practice in the engineer
8、ing/constructionprofession to concurrently use pounds to represent both a unitof mass(lbm)and of force(lbf).This implicitly combines twoseparate systems of units:that is,the absolute system and thegravitational system.It is scientifically undesirable to combinetwo separate sets of inch-pound units w
9、ithin a single standard.As stated,this standard includes the gravitational system ofinch-pound units and does not use/present the slug unit formass.However,the use of balances or scales recording poundsof mass(lbm)or recording in lbm/ft3shall not be regarded asnonconformance with this standard.1.5 C
