ASTM C418 – Standard Test Method for Thermal Diffusivity by the Flash Method Standard Test Method for Abrasion Resistance of Concrete by Sandblasting
Description:
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.
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.
