FACTORS AFFECTING THE TENSILE CREEP OF CONCRETE

PREVIOUS RESEARCH INTO TENSILE CREEP BEHAVIOR IS REVIEWED AND DISCUSSED IN TERMS OF THE PARAMETERS ASSOCIATED WITH DISCUSSIONS OF COMPRESSIVE CREEP BEHAVIOR. TENSILE CREEP IS DISCUSSED IN TERMS OF THE FACTORS AFFECTING COMPRESSIVE CREEP BEHAVIOR: MAGNITUDE OF APPLIED STRESS, AMBIENT HUMIDITY AND TEMPERATURE, PASTE CONTENT, AGGREGATE TYPE AND GRADING, AGE AT LOADING, AND CEMENT TYPE. EXPERIMENTAL INVESTIGATION OF THE PHENOMENON OF TENSILE CREEP IS LIMITED BECAUSE OF THE DIFFICULTIES RELATED IN THE EXPERIMENTAL TECHNIQUE, I.E. LOAD APPLICATION AND STRAIN MEASUREMENT. ALTHOUGH THE MECHANISM OF CREEP IN CONCRETE IS NOT YET FULLY UNDERSTOOD, IT IS GENERALLY ACCEPTED THAT THE MECHANISMS OF CREEP IN TENSION AND COMPRESSION ARE SIMILAR. ON THIS BASIS, IT IS IMPLIED THAT THE PARAMETERS THAT INFLUENCE THE MAGNITUDE OF COMPRESSIVE CREEP ALSO WILL AFFECT THE MAGNITUDE OF TENSILE CREEP. DUE TO DIFFICULTIES ASSOCIATED WITH THE EXPERIMENTAL TECHNIQUE, THE TEST DATA PRESENTED ARE LIMITED AND IN SOME CASES, CONTRADICTORY.
