EARLIER DETERMINATION OF CONCRETE STRENGTH POTENTIAL

A WORLD WIDE REVIEW IS PRESENTED OF ACCELERATED STRENGTH TESTING PROCEDURES THAT HAVE BEEN, OR ARE BEING USED, TO OBTAIN AN EARLIER ESTIMATE OF THE 28-DAY COMPRESSIVE STRENGTH OF CONCRETE. A NEW PROCEDURE, AUTOGENOUS CURING, IS DESCRIBED IN WHICH THE STRENGTH DEVELOPMENT OF A CONCRETE TEST CYLINDER IS ACCELERATED BY CURING IN A WELL INSULATED CONTAINER THAT RETAINS PART OF THE HEAT OF HYDRATION. THE WHOLE CONCEPT OF USING 28-DAY COMPRESSIVE STRENGTH AS A BASIS FOR JUDGING THE ACCEPTABILITY OR STRENGTH POTENTIAL OF CONCRETE IS QUESTIONED. IT IS ARGUED THAT AN ACCELERATED STRENGTH TEST COULD PROVIDE INFORMATION EQUALLY AS VALID, AT LEAST 26 DAYS SOONER. /AUTHOR/
