PORTLAND CEMENT CONCRETE-RESEARCH, TESTING, AND PERFORMANCE

SELECTED ASPECTS OF THE STATE-OF-THE-ART OF THE PREDICTION OF PERFORMANCE OF PORTLAND CEMENT CONCRETE IN SERVICE ARE CRITICALLY REVIEWED. THE ROLE OR RESEARCH IN EVALUATING PERFORMANCE AND IN GUIDING THE DEVELOPMENT OF TESTS IS DISCUSSED. IT IS CONCLUDED THAT, WHILE REMARKABLE PROGRESS HAS BEEN MADE, MUCH REMAINS TO BE DONE TO PROVIDE BASIC AND FUNDAMENTAL KNOWLEDGE OF THE PHENOMENA, THE SUBSTANCES, AND THE ENVIRONMENT OF SERVICE. A BETTER UNDERSTANDING OF THE NATURE AND FORMATION PROCESSES OF THE BONDS THAT GIVE CONCRETE STRENGTH, THE PROCESSES BY WHICH THESE BONDS BECOME BROKEN, AND THE CRITICAL LEVELS OF INTERACTING ENVIRONMENTAL FACTORS THAT PRODUCE IRREVERSIBLE CHANGES IN CONCRETE IN SERVICE IS CRITICALLY NEEDED. SUCH RESEARCH RESULTS WILL PERMIT THE PLANNING OF EXPERIMENTS THAT WILL YIELD DATA TO ESTABLISH RELATIONS BETWEEN LEVELS OR RELEVANT PROPERTIES AND PERFORMANCE IN LEVELS OF ENVIRONMENTAL INFLUENCES. FROM SUCH RELATIONS, PERFORMANCE MAY BE PREDICTED; FROM SUCH PREDICTIONS, PERFORMANCE MAY BE PREDICTED; FROM SUCH PREDICTIONS, TEST METHODS AND SPECIFICATIONS CAN BE ESTABLISHED. /AUTHOR/
