WATER BATH ACCELERATED CURING OF CONCRETE

WATER BATH METHODS FOR ACCELERATING THE STRENGTH DEVELOPMENT OF PORTLAND CEMENT CONCRETE WERE INVESTIGATED. THE THREE METHODS STUDIED CONSISTED OF: CURING IMMEDIATELY AFTER CASTING IN 95 F WATER FOR 24 HOURS; CURING IN BOILING WATER FOR 3-1/2 HOURS, COMMENCING 23 HOURS AFTER CASTING; AND CURING IN BOILING WATER FOR 15 HOURS COMMENCING AFTER THE CONCRETE REACHED A PENETRATION RESISTANCE OF 3500 PSI (FIXED SET). ALSO STUDIED WERE THE EFFECTS ON THE RESULTS OF THE FIXED SET ACCELERATED CURING METHODS OF CURING WATER TEMPERATURES FROM 95F TO 212F. THE FIXED SET BOILING METHOD IS THE MOST EFFICIENT AND RELIABLE OF THOSE STUDIED. WATER BATH ACCELERATED CURING IS MORE EFFICIENT FOR HIGH THAN FOR LOW STRENGTH CONCRETES. WATER BATH AND STANDARD MOIST CURING PRODUCE STRENGTH RESULTS OF ABOUT EQUAL REPRODUCIBILITY. ACCELERATED CURING EFFICIENCIES ARE DIRECTLY PROPORTIONAL TO THE TOTAL RELATIVE AMOUNTS OF HEAT RELEASED BY THE CONCRETES DURING ACCELERATED CURING. OPTIMUM WATER BATH TEMPERATURES FOR ACCELERATED CONCRETE STRENGTH DEVELOPMENT RANGE APPROXIMATELY FROM 165 DEGREES TO 180F. /AUTHOR/
