IMPORTANCE OF PETROGRAPHIC IDENTIFICATION OF NATURAL AGGREGATES

NATURAL AGGREGATES SHOULD BE PETROGRAPHICALLY IDENTIFIED IN ORDER TO DETERMINE THE ROCKS AND MINERALS PRESENT, TO SINGLE OUT THE HARMFUL CONSTITUTENTS, TO CORRELATE THE AGGREGATE CONSTITUENTS WITH THE STANDARD-ACCEPTANCE-TEST RESULTS USED IN EVALUATION OF THE AGGREGATES, AND TO COMPARE THE AGGREGATES WITH THOSE OF A KNOWN BEHAVIOR. PETROGRAPHIC ASSESSMENT OF AN AGGREGATE IS USUALLY NOT FINAL, BUT IT IS AN ESSENTIAL CONTRIBUTION TO THE EVALUATION. THE FINAL DECISION OF WHETHER OR NOT TO USE A PARTICULAR SOURCE OF AGGREGATE IS MADE ON THE BASIS OF BOTH ACCEPTANCE TESTS AND PETROGRAPHIC EXAMINATION IN ACCORDANCE WITH SPECIFICATIONS FOR THE PARTICULAR STRUCTURE AND ON THE BASIS OF ECONOMIC CONSIDERATIONS. /AUTHOR/
