CONCRETE AGGREGATES SHAPE, SURFACE TEXTURE, AND COATINGS. IN: INVESTIGATING CONCRETE. SELECTED WORKS OF BRYANT AND KATHARINE MATHER

This paper describes how, engineers who are required to evaluate the concrete-making properties of aggregates or to discuss the factors responsible of variations in the behavior of concrete are generally aware that variations in aggregate particle shape, surface texture, and coatings may produce effects of significance to these considerations. They have not been provided with adequate information with which to convert their general awareness of the potential significance of these variations into useful tools that they can employ in making engineering judgments. To provide such information, it will be necessary for scientists, engineers, and technologists concerned with these questions to: (1) develop adequate definitions and concepts of the properties; (2) develop suitable techniques for determining the degree which aggregates differ with respect to them; and (3) determine the effects of such differences on the behavior of concrete. The results of such work may justify the use of aggregates that are now regarded as unsuitable, and may cause the establishment of new requirements for aggregates. In any case, the results of such work will contribute knowledge to an area in which there is now very little.
