PREDICTION OF FLY ASH PERFORMANCE

IT IS SHOWN THAT THERE IS A HIGH DEGREE OF CORRELATION AMONG CERTAIN PROPERTIES OF FLY ASH, WHICH PERMITS THE USE OF MULTIPLE FACTOR ANALYSIS TO PREDICT THE PERFORMANCE OF FLY ASH IN CEMENT, MORTARS, AND CONCRETE. THE ADVANTAGES OF THIS TECHNIQUE TO PRODUCERS AND USERS OF FLY ASH ARE THAT THE BEHAVIOR OF FLY ASH IN MORTAR AND CONCRETE COMPOSITIONS IS MORE CLEARLY EXPLAINED; SPECIFICATIONS CAN BE SIMPLIFIED, BOTH WITH RESPECT TO THE NUMBER OF DIFFERENT TESTS THAT MAY BE REQUIRED AND TO THE EXPENSE OF RUNNING THE TESTS, AND IN CERTAIN CASES LABORATORY TESTS INVOLVING LONG TERM CURE PERIODS CAN BE ELIMINATED; AND CONFLICTING STATEMENTS AND CONCLUSIONS MADE IN PREVIOUSLY REPORTED STUDIES CAN BE RESOLVED. VISUAL COMPARISONS OF SAMPLES OF FLY ASH UNDER MICROSCOPIC EXAMINATION SUPPORT THE MATHEMATICAL FINDINGS.
