1、Designation:D510209Standard Test Methods forUnconfined Compressive Strength of Compacted Soil-LimeMixtures1This standard is issued under the fixed designation D5102;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last rev
2、ision.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 preparing,curing,and testing laboratory-compacted specimens of soil-lime and other lime-tre
3、ated materials(Note 1)for determiningunconfined compressive strength.This test method can be usedfor specimens prepared at the maximum unit weight andoptimum water content,or for specimens prepared at othertarget unit weight and water content levels.Other applicationsare given in Section 5 on Signif
4、icance and Use.NOTE1Lime-based products other than commercial quicklime andhydrated lime are also used in the lime treatment of fine-grained cohesivesoils.Lime kiln dust(LKD)is collected from the kiln exhaust gases bycyclone,electrostatic,or baghouse-type collection systems.Some limeproducers hydrat

7、 testing laboratories.Procedure B is considered toprovide relative measures of individual specimens in a suite oftest specimens rather than standard compressive strengthvalues.Because of the lesser height-to-diameter ratio(1.15)ofthe cylinders,compressive strength determined by Procedure Bwill norma
8、lly be greater than that by Procedure A.1.3.3 Results of unconfined compressive strength tests usingProcedure B should not be directly compared to those obtainedusing Procedure A.1.4 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inP
9、ractice D6026.1.4.1 The 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.1.5 Lime is
10、 not an effective stabilizing agent for all soils.Some soil components such as sulfates,phosphates,organics,etc.can adversely affect soil-lime reactions and may affect thetest results using this method.1.6 The values stated in either SI units or inch-pound unitsare to be regarded separately as stand
11、ard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.6.1 The gravitational system of inch-pound units is usedwhen dealing with inch-pound un
12、its.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.1.6.2 It is common practice in the engineering/constructionprofession to concurrently use pounds to represent both
13、 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 combinethe use of two separate sets of inch-pound units within a singlestandard.As stated,this standard includes the
14、gravitationalsystem of inch-pound units and does not use/present the slugunit for mass.However,the use of balances or scales recordingpounds of mass(lbm)or recording density in lbm/ft3shall notbe regarded as non-conformance with this standard.1These test methods are under the jurisdiction ofASTM Com
