Abstract

A property of aggregate may be considered significant, from the viewpoint of this publication, only if it has a significant effect on the behavior of portland-cement concrete in service. Similarly, a test of aggregate may be considered significant only if it yields useful information about a significant property or group of properties. The behavior of concrete in service is determined by the interaction of certain of its properties and the significant characteristics of the exposure to which it is subjected. Variations in shape and surface texture of, or the presence of coatings on, aggregate particles may significantly affect properties of concrete that are important to its behavior in service.
