ASTM C1138M-05

Standard Test Method for Abrasion Resistance of Concrete (Underwater Method)

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 0). This procedure simulates the abrasive action of waterborne particles (silt, sand, gravel, and other solids). Note 0Other procedures are available for measuring abrasion resistance of concrete surfaces not under water. These include Test Methods C 418, C 779, and C 944.
1.2 The values stated in acceptable metric units are to be regarded as the standard.
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. (Warning-Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)
