    Withdrawn Rationale:

    This practice covers the laboratory preparation of chemically grouted soil specimens for use in laboratory tests to determine engineering parameters.

    Formerly under the jurisdiction of Committee D18 on Soil and Rock, this practice was withdrawn in January 2018 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

    1. Scope

    1.1 This practice covers the laboratory preparation of chemically grouted soil specimens for use in laboratory tests to determine engineering 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.

    1.2 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 D4219 and D5202.

    1.3 This practice requires the injection of grout into soil specimens already fabricated to a desired density.

    1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.

    1.4.1 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.

    1.5 The values stated in either SI units or inch-pound units [presented in brackets] are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

    1.5.1 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 is not given, unless dynamic (F = ma) calculations are involved.

    1.6 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 projects 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.

    1.7 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.
