ASTM D 559 Document Information:
Title
Standard Test Methods for Wetting and Drying Compacted Soil-Cement Mixtures
ASTM International
Publication Date:
Feb 10, 2003
Scope:
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 water content using the compaction procedure
described in Test Methods D 558.
Two test methods, depending on soil gradation, are covered for
preparation of material for molding
specimens and for molding specimens as follows:
All observed and calculated values shall conform to the guidelines for
significant digits and
rounding established in Practice D 6026.
The values stated in inch-pound units are to be regarded as standard,
except as noted below. The
values given in parentheses are mathematical conversions to SI units,
and are provided for
information only and are not considered standard.
The gravitational system of inch-pound units is used when dealing with
inch-pound units. In this
system, the pound (lbf) represents a unit of force (weight), while the
unit for mass is slugs.
The slug unit of mass is almost never used in commercial 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 equivalent inch-pound unit (slug) is not given.
It is common practice in the engineering/construction profession to
use pounds to represent both a
unit of mass (lbm) and of force (lbf). This implicitly combines two
separate systems of units; that
is, the absolute system and the gravitational system. It is
scientifically undesirable to combine
the use of two separate sets of inch-pound units within a single
standard. As stated in 1.4.2, this
standard includes the gravitational system of inch-pound units and
does not use/present the slug
unit for mass. However, the use of balances or scales recording pounds
of mass (lbm) or recording
density in lbm/ft³ shall not be regarded as nonconformance with
this standard.
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.
