A NEW APPROACH TO THE PREDICTION OF TRUE ULTIMATE STRENGTH OF CONCRETE

CONCRETE HAS BEEN OBSERVED TO FAIL UNDER A LOAD LESS THAN THAT OF ITS ULTIMATE STRENGTH, AS GIVEN BY THE SHORT-TIME COMPRESSION TEST, WHEN THE LOAD IS SUSTAINED FOR A SUFFICIENTLY LONG TIME. A CORRECT KNOWLEDGE OF THIS SUSTAINED LOAD STRENGTH OR TRUE ULTIMATE STRENGTH IS ESSENTIAL FOR THE DETERMINATION OF SAFETY OF A STRUCTURE. THE PAPER BRIEFLY OUTLINES THE PREVIOUSLY PUBLISHED METHODS FOR ESTIMATING THIS TRUE ULTIMATE STRENGTH. A NEW SIMPLE METHOD FOR THE ESTIMATION OF TRUE ULTIMATE STRENGTH FROM THE RESULTS OF A SHORT-TIME TEST BASED ON A STUDY OF THE VARIATION OF RATE OF STRAIN WITH APPLIED LOAD IS PRESENTED. RESULTS OF AN EXPERIMENTAL INVESTIGATION COMPARING THE TRUE ULTIMATE STRENGTH ESTIMATED BY THE NEW METHOD WITH THAT OBTAINED BY TWO OTHER METHODS ARE ALSO GIVEN. /AUTHOR/
