Standard Practice for Use of Foundry Sand in Structural Fill and Embankments
ORDER

Scope

1.1 This practice covers methods to use foundry sand as embankment and structural fill.

1.2 It includes recommended construction (Section 5), compaction control (Section 6), and freeze-thaw durability (Section 7) practices.

1.3 The engineer should be aware that foundry sand is a by-product of metal casting industries. Various state, county, and local environmental laws and regulations may apply if foundry sand is used as an alternative embankment or fill material. It is advised that foundry sand users contact state, county, and local environmental regulators to determine what requirements or limitations may exist.

1.4 This standard applies to both green foundry sand and chemically bonded foundry sand.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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.

1.7 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.

Significance and Use

4.1 Earthwork associated with highway construction provides an opportunity for high volume reuse of green foundry sands discarded by the foundry industry. This practice covers methods and recommendations to use of foundry sand as embankment and structural fill.

4.2 This practice describes the unique construction considerations that may apply to foundry sands. The behavior may vary due to specific composition of the material and local conditions.

4.3 The use of foundry sand in embankment and structural fill may be regulated by state and local codes. These codes should be consulted.

4.4 This practice is intended for use with green foundry sands where bentonite is used as the binder. It may not be applicable for chemically bonded foundry sands.
