EFFECTS OF SHORT-TIME VARIATIONS IN THE ENVIRONMENTAL CONDITIONS UPON CREEP OF CONCRETE

IT IS WELL KNOWN THAT THE SLOW DEFORMATIONS OF CONCRETE ARE INFLUENCED BY A VERY HIGH NUMBER OF FACTORS: QUALITY OF THE CONCRETE CASTING, DIMENSIONS AND SHAPE OF THE SAMPLES, HUMIDITY, TIME, AND INTENSITY OF THE LOAD. THIS PAPER, ON THE BASIS OF EXPERIMENTAL TESTS, INDICATES HOW IN SOME CASES THE REAL CREEP CHARACTERISTICS OF A GIVEN CONCRETE DEPEND SIGNIFICANTLY ON THE ENVIRONMENTAL CONDITIONS TO WHICH THE CONCRETE IS SUBMITTED. SUCH CHANGES PRODUCE AN INCREASE IN CREEP, EVEN IN CASES WHERE THE CONCRETE IS SUBJECTED TO A LEVEL OF SUSTAINED LOADING STRESS BELOW ITS PLASTIC LIMIT. THE SOONER THE CONCRETE IS LOADED AND THE EARLIER THE CHANGE IN ENVIRONMENTAL CONDITIONS TAKES PLACE, THE LARGER IS THE INCREASE IN CREEP. MOST OF THE INCREASE IN CREEP DUE TO CHANGES IN TEMPERATURE AND HUMIDITY IS OF AN IRRECOVERABLE NATURE.
