ASTM D 5202 Document Information:
Title
Standard Test Method for Determining Triaxial Compression Creep Strength of Chemical Grouted Soils
ASTM International
Publication Date:
Jan 1, 2008
Scope:
This test method covers the determination of long-term strength
and deformation of a cylindrical specimen of either a (undisturbed)
field sample or laboratory-fabricated chemical grouted soil when it
is sheared undrained in compression under a constant sustained
load.
NOTE 1—The voids of chemical grouted soils are most often
substantially filled with grout. Thus, pore pressures are unlikely
to develop. This test method is not applicable to partially grouted
soils in which substantial pore pressures may develop. If pore
pressures must be measured, reference is made to Test Method D 4767
for equipment and procedures.
This test method provides data useful in determining strength
and deformation properties of chemical grouted soils subjected to
sustained loads. Mohr strength envelopes may also be
determined.
The determination of strength envelopes and the development of
relationships to aid in interpreting and evaluating test results
are left to the engineer or office requesting the test.
The values stated in either SI or inch-pound units shall be
regarded separately as standard. The values in each system may not
be exact equivalents, therefore, each system must be used
independently of the other, without combining values in any
way.
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.
This test method 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.
