EFFECT OF CURING CONDITION ON COMPRESSIVE STRENGTH OF CONCRETE TEST SPECIMENS

COMBINATIONS OF CURING CONDITIONS WERE TESTED SIMULATING TYPICAL NON-STANDARD EXPOSURES IN THE FIELD IN COMPARISON WITH STANDARD CURING. A SINGLE CLASS OF CONCRETE WAS EMPLOYED, DESIGNED TO CONTAIN 5.5 SACKS OF CEMENT PER CUBIC YARD, TO HAVE A SLUMP OF 3 TO 4 INCHES, WITH A FINENESS MODULUS OF COMBINED AGGREGATE OF 5.25. THE EFFECTS WERE STUDIED OF INADEQUATE PROTECTION DURING THE INITIAL CURING PERIOD. ANOTHER GROUP OF TESTS WERE CONDUCTED COMPARING THE EFFECTS OF FAVORABLE AND UNFAVORABLE CURING CONDITIONS ON STRENGTH OF CONCRETE MADE WITH A PORTLAND CEMENT, A SLAG CEMENT, A PORTLAND-FLY-ASH BLEND AND PORTLAND CEMENT WITH CALCIUM CHLORIDE. DATA DEMONSTRATE THAT LARGE PENALTIES IN STRENGTH MAY RESULT FROM DEPARTURES FROM STANDARD CURING REQUIREMENTS. STRENGTHS SPECIFICATIONS CANNOT BE MET WHEN SPECIMENS ARE TREATED IN ACCORDANCE WITH STANDARD PROCEDURES. THE CEMENT BLENDS WERE MORE ADVERSELY AFFECTED BY UNFAVORABLE CURING CONDITIONS THAN REGULAR PORTLAND CEMENT. RESULTS ARE PRESENTED OF THE COMPRESSIVE STRENGTH TESTS.
