This paper reviews the effects of important factors such as strength of concrete, mixture proportioning, selection of concrete-making materials, finishing procedures, and surface treatment on the wear resistance of concrete surfaces as determined by recent research. Newly revised or developed ASTM standards, Test for Abrasion Resistance of Concrete by Sandblasting (C 418) and Test for Abrasion Resistance of Horizontal Concrete Surfaces (C 779), provide test procedures for various types of wear simulating erosive or abrasive actions.
