Description / Abstract:
These methods of test are intended for determining the relation
between moisture content and density of soil-cement mixtures when
compacted before cement hydration as prescribed.
A 944-cm3 (1/30-ft3) mold and a 2.5-kg
(5.5-lb) rammer dropped from a height of 305 mm (12 in.) are used
and two methods, depending on soil gradation, are covered, as
follows:
Method A—Soil material passing a 4.75-mm (No. 4) sieve.
This method shall be used when 100 percent of the soil sample
passes the 4.75-mm (No. 4) sieve; or
Method B—Soil material passing a 19.0-mm (¾-in.) sieve.
This method shall be used when part of the soil sample is retained
on the 4.75-mm (No. 4) sieve.
This test method applies to soil-cement mixtures that have 30
percent or less retained on the 19.0-mm (¾-in.) sieve, when Method
B is used. The material retained on these sieves shall be defined
as oversized particles (coarse particles).
The following applies to all specified limits in this standard:
For the purposes of determining conformance with these
specifications, an observed value or a calculated value shall be
rounded off "to the nearest unit" in the last right-hand place of
figures used in expressing the limiting value, in accordance with
ASTM E 29.
