METHOD FOR EARLY PREDICTION OF CONCRETE STRENGTH

AN ACCELERATED TEST TO DETERMINE THE COMPRESSIVE STRENGTH OF CONCRETE HAS BEEN MADE URGENT BY THE ADVENT OF PRESTRESSED CONCRETE. THE METHOD PROPOSED IN THIS ARTICLE REQUIRES 28 1/2 HOURS BETWEEN MOULDING AND TESTING AND PREDICTS 28 DAY STRENGTH TO AN ACCURACY OF PLUS OR MINUS 12%. THIS METHOD UTILIZES BOILING WATER AS A CURING AGENT FOR THE CYLINDERS. THE 12% ACCURACY IS CONSIDERED SUFFICIENT FOR ROUTINE QUALITY CONTROL. /CGRA/
