Significance and Use | ||||||||||||
4.1 This test method covers the laboratory evaluation of the relative resistance of concrete surfaces to abrasion. This procedure simulates the action of waterborne abrasives and abrasives under traffic on concrete surfaces. It performs a cutting action that tends to abrade more severely the less resistant components of the concrete. |

1. Scope | ||||||||||||
1.1 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. 1.2 The values stated in SI units are to be regarded as the standard. Inch-pound units are shown for information purposes in parentheses. 1.3 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard. 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, health, and environmental 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 Test Methods C779/C779M, C944/C944M, and C1138M. The test method most closely
representing service conditions should be used.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
