3、erelationship between the water content and the density ofsoil-cement mixtures when compacted before cement hydra-tion as prescribed.1.2 A130-ft3(944-cm3)mold and a 5.50-lbf(24.5-N or massof 2.49-kg)rammer dropped from a height of 12.0 in.(30.5 cm)are used and two methods,depending on soil gradation

5、etained onthe No.4(4.75-mm)sieve.This test method may be used only onmaterials with 30%or less retained on the34-in.(19.0-mm)sieve81.3 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.4 The values stated in inch-poun
6、d units are to be regardedas standard,except as noted below.The values given inparentheses are mathematical conversions to SI units that areprovided for information only and are not considered standard.1.4.1 The gravitational system of inch-pound units is usedwhen dealing with inch-pound units.In th
7、is 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 equiv
8、alent inch-pound unit(slug)is not given.1.4.3 It is common practice in the engineering/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
9、.It is scientifically undesirable to combinethe use of two separate sets of inch-pound units within a singlestandard.As stated in 1.4.2,this standard includes the gravita-tional system of inch-pound units and does not use/present theslug unit for mass.However,the use of balances or scalesrecording p
10、ounds of mass(lbm)or recording density in lbm/ft3shall not be 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
