Significance and Use
4.1 This test method is intended to qualitatively simulate the behavior of swirling water containing suspended and transported solid objects that produce abrasion of concrete and cause potholes and related effects.
4.2 This test method should provide a relative evaluation of the resistance of concrete to such action.
4.3 The results are expected to be useful in selection of materials, mixtures, and construction practices for use where such action is to be expected.
4.4 The test method is not intended to provide a quantitative measurement of the length of service that may be expected from a specific concrete.
Scope
1.1 This test method covers a procedure for determining the relative resistance of concrete (including concrete overlays and impregnated concrete) to abrasion under water (see Note 1). This procedure simulates the abrasive action of waterborne particles (silt, sand, gravel, and other solids).
Note 1: Other procedures are available for measuring abrasion resistance of concrete surfaces not under water. These include Test Methods C418, C779/C779M, and C944/C944M.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents: therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
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. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)
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.
