Standard Test Methods for Wetting and Drying Compacted Soil-Cement Mixtures

SCOPE
1.1 These test methods cover procedures for determining the soil-cement losses, water content changes, and volume changes (swell and shrinkage) produced by repeated wetting and drying of hardened soil-cement specimens. The specimens are compacted in a mold, before cement hydration, to maximum density at optimum moisture content using the compaction procedure described in Test Methods D 558.  
1.2 Two test methods, depending on soil gradation, are covered for preparation of material for molding specimens and for molding specimens as follows:  Sections Test Method A, using soil material passing a No. 4 (4.75-mm) sieve. This method shall be used when 100% of the soil sample passes the No. 4 (4.75-mm) sieve 5 Test Method B, using soil material passing a 3/4-in. (19.0- mm) sieve. This method shall be used when part of the soil sample is retained on the No. 4 (4.75-mm) sieve 6
1.3 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
