PREDICTION OF CREEP IN STRUCTURAL CONCRETE

THE GENERAL OBJECTIVE OF THIS REPORT WAS TO PRESENT A PROCEDURE TO PREDICT THE CREEP THAT WILL OCCUR IN STRUCTURAL CONCRETE UNDER VARIOUS ENVIRONMENTAL CONDITIONS. ALSO, TO PRESENT INFORMATION ON THE VISCOUS NATURE OF CONCRETE, THE MECHANISM OF CREEP, AND A THEORETICAL MODEL REPRESENTING THIS BEHAVIOR. CHANGES IN THE COMPOSITION OR ENVIRONMENT OF THE CONCRETE WILL AFFECT ITS VOLUME STABILITY. SOME OF THE FACTORS WHICH INFLUENCE ITS VOLUME STABILITY ARE: MIX CONSTITUENTS AND PROPORTIONS, MIXING TIME AND CONSOLIDATION, AGE AT LOADING, MOISTURE CONTENT, STRESSES, AMBIENT AIR CONDITION, SIZE OF SPECIMEN, STRENGTH AND REINFORCEMENT. CREEP OF CONCRETE IS DIVISIBLE INTO TWO COMPONENTS REFERRED TO AS BASIC CREEP AND DRYING CREEP. BASIC CREEP IS THAT PART OF CREEP WHICH OCCURS INDEPENDENTLY OF THE LOADED SPECIMEN'S MOISTURE GAIN OR LOSS. DRYING OR WETTING CREEP IS CREEP WHICH RESULTS FROM SIMULTANEOUS MOISTURE LOSS OR GAIN OF THE LOADED SPECIMEN. INVOLVED AND COMPLICATED FORMULAS FOR PREDICTING BOTH BASIC AND DRYING CREEP ARE GIVEN. /BPR/
