ASTM D 4320 Document Information:
Title
Standard Practice for Laboratory Preparation of Chemically Grouted Soil Specimens for Obtaining Design Strength Parameters
ASTM International
Publication Date:
Nov 1, 2004
Scope:
(Footnote *)
This practice covers the laboratory preparation of chemically grouted
soil specimens for use in
laboratory tests to determine design strength parameters.
NOTE 1 - This practice may not be applicable to grout mixtures with
gel times shorter than the time
required to saturate the specimen with grout.
The specimens are intended for both strength and modulus determination
in unconfined and confined
compression testing.
NOTE 2 - Preparation methods for specimens to be used for other
purposes are described in Test
Methods D 4219 and D 5202.
This practice requires the injection of grout into soil specimens
already fabricated to a desired
density.
All observed and calculated values shall conform to the guidelines for
significant digits and
rounding established in Practice D 6026.
The method used to specify how data are collected, calculated, or
recorded in this standard is not
directly related to the accuracy to which the data can be applied in
design or other uses, or both.
How one applies the results obtained using this standard is beyond its
scope.
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,
which are provided for
information only and are not considered 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
requirements prior to use.
This practice offers a set of instructions for performing one or more
specific operations. This
document cannot replace education or experience and should be used in
conjunction with professional
judgment. Not all aspects of this practice may be applicable in all
circumstances. This ASTM
standard is not intended to represent or replace the standard of care
by which the adequacy of a
given professional service must be judged, nor should this document be
applied without
consideration of a project's many unique aspects. The word "Standard"
in the title of this document
means only that the document has been approved through the ASTM
consensus process.
The text of this standard references notes and footnotes which provide
explanatory material. These
notes and footnotes (excluding those in tables and figures) shall not
be considered as requirements
of the standard.

standard.
