This test method covers determination of the abrasion resistance characteristics of concrete by subjecting it to the impingement of air-driven silica sand. It is intended for use as a basis for the development of informed judgment.

The values stated in SI units are to be regarded as the standard. Inch-pound units are shown for information purposes in parentheses.

This standard does not purport to address 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.

NOTE 1-Users of this test method are advised that there are known safety hazards associated with the use of silica as a blasting media. Consult the silica manufactures MSDS to insure that the latest recommended health and safety practices are being followed.

NOTE 2-Other procedures are available for measuring abrasion resistance of concrete surfaces in addition to subjecting it to air driven silica sand. Consideration should be given to other methods of testing as outlined in ASTM C779/C779M, ASTM C944, and ASTM C1138. The test method most closely representing service conditions should be used.

The text of this standard references notes and footnotes which are provided as explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.
