Description / Abstract:

(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.

Footnote * - A Summary of Changes section appears at the end of this standard.
