STRENGTH DEVELOPMENT OF CONCRETE EXPOSED IN WINTER
THE RELATIONSHIP OF THE STRENGTH OF STANDARD LABORATORY-CURED CYLINDERS TO THE STRENGTH OF CONCRETE IN COLUMNS AND SLABS AND TO FIELD-CURED CYLINDERS EXPOSED UNDER WINTER CONDITIONS HAVE BEEN REPORTED. THE COLUMNS, SLABS, AND ABOUT HALF OF THE CYLINDERS WERE LEFT AT AN OUTDOOR EXPOSURE SITE AFTER AN INITIAL 3-DAY CURING AT 50 PLUS OR MINUS 10 DEGREES F(10 PLUS OR MINUS 6 DEGREE C) THE REMAINING CLYINDERS WERE STANDARD-CURED. CORES WERE TAKEN FROM THE COLUMNS AND SLABS AT 3 DAYS, 14 DAYS, 28 DAYS , 120 DAYS, AND 355 DAYS FOR TESTING IN COMPRESSION. THE TEST RESULTS SHOW THAT CONCRETE INITIALLY CURED FOR 3 DAYS AT ABOUT 50 DEGREE F (10 DEGREE C) AND ABOUT 75, RELATIVE HUMIDITY AND THEN EXPOSED TO BELOW FREEZING TEMPERATURES CONTINUES TO GAIN STRENGTH. THE RATE OF STRENGTH GAIN OF THE FIELD-CURED CONCRETE SHOWS A MARKED INCREASE AFTER THE AMBIENT AIR TEMPERATURE EXCEEDS 50 DEGREE F (10 DEGREE C). AT THE AGE OF ABOUT 1 YR, THE COMPRESSIVE STRENGTHS OF THE FIELD-CURED CONCRETE GENERALLY EXCEEDED THE STANDARD STRENGTH. /ASCE/ME/
