AGGREGATE CHARACTERISTICS AND THEIR EFFECT ON PORTLAND CEMENT CONCRETE

THERE ARE VOLUMES OF IMFORMATION REGARDING THE EFFECT OF AGGREGATE CHARACTERISTICS ON THE QUALITY AND BEHAVIOR OF PORTLAND CEMENT CONCRETE. UNFORTUNATELY, HOWEVER, THIS BODY OF KNOWLEDGE IS NOT NORMALLY COMPLETELY EMPLOYED WHEN SELECTING CONCRETE AGGREGATES FOR USE. THERE IS A TENDENCY TO RELY TOO HEAVILY ON AND INTERPRET TOO PRECISELY THE RESULTS OF THE STANDRAD ACCEPTANCE TESTS, TESTS WHICH WERE DESIGNED AND INTENDED ONLY TO PROVIDE GUIDENCE TO THE EXERCISING OF ENGINEERING JUDGEMENT. FINALLY, AND PROBABLY MOST OBVIOUSLY, CONCRETE TECHNOLOGISTS TEND TO EMPLOY THE BULT OF THEIR KNOWLEDGE TO RESEARCH THE MANIFESTATIONS OF AGGREGATE AND CONCRETE FAILURES AND, ONLY AFTER SUCH A MANIFESTATION, FOR THE PREVENTION OF ANY RECURRENCE. THERE IS A REAL NEED FOR COMPREHENSIVE, WELL FOUNDED, AND TRULY INFORMATIVE TESTING PROCEDURES, PROCEDURES WHICH ARE BETTER KEYED TO CONCRETE PERFORMANCE AND BEHAVIOR. /AUTHOR/
