ASTM D6236-98

1.1 This guide covers guidance for obtaining cores of cement or lime stabilized soil for use in determining compressive strength, lift thickness and bond strength, and other physical properties. This guide is primarily for use in coring through shallow (0.3 to 3 meter (1 to 10ft) thick) layers of cement or lime stabilized soils containg particles < 50 mm (2 in.) in diameter to the underlying foundation.

Note 1-This guide could be used for some Class C in self cementing fly ash materials which may also stabilize soil.

1.2 This guide does not cover material of less than 2070 kPa (300 psi) compressive strength such as cement-soil-bentonite mixtures or some controlled low strength materials (CLSM).

1.3 The values stated in SI units are to be regarded as the standard. Other values are examples or for information only.

1.4 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. Specific precautionary statements are given in Section 8.

1.5 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide 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.
