Title: Method Of Petrographic Examination Of Aggregates For Concrete

Author(s): Katharine Mather and Bryant Mather

Publication: Symposium Paper

Volume: 223


Appears on pages(s): 155-183


Date: 10/1/2004

A detailed description of the method for petrographic examination of aggregates for concrete as it has been developed for use by the Concrete Laboratories of the Corps of Engineers is presented. The differences in procedure which depend upon the nature of the sample submitted and the purposes of the examination are described. Suggestions are made concerning the features to be delineated, the amount of material to be examined, and the organization and presentation of the results of the examination. It is hoped that the information presented will serve to clarify the concept of what is meant by petrographic examination of aggregates and, perhaps, ultimately, contribute to greater uniformity in the making of such examinations.
