ASTM D 4320 : 1993

1.1 This test method covers the laboratory preparation of chemically grouted soil specimens for use in laboratory tests to determine design strength parameters.

Note 1-This test method 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 test method requires the injection of grout into soil specimens already fabricated to a desired density.

1.4 The values stated in inch-pound units are to be regarded as the standard.

1.5 This standard does not purport to address all of the safety problems, 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.
