THE INTERPRETATION OF CREEP TESTS ON CONCRETE /IN FRENCH/

THE ROLE OF ADSORBED WATER IN CREEP IS NOT ALWAYS UNDERSTOOD. STRONGLY ADSORBED WATER IS A STRUCTURAL LOAD BEARING COMPONENT; ITS QUANTITY AND STATE OF STRESS CAN VARY WHEN THE SYSTEM CHANGES FROM ONE MECHANICAL EQUILIBRIUM TO ANOTHER. THIS CHARACTERISTIC OF ADSORBED WATER MUST BE TAKEN INTO ACCOUNT IN REVERSIBLE CREEP. A SIMPLE NEW RHEOLOGICAL MODEL SHOWS UNDER WHAT CONDITIONS MECHANICAL AND THERMODYNAMIC EQUILIBRIUM IS REESTABLISHED AFTER ONE LOAD HAS BEEN APPLIED AND REMOVED. LOSS & GAIN OF WATER OCCUR IN REVERSIBLE CREEP. CREEP DOES NOT TRANSFER THE STRESS IN WATER TO THE SOLID STRUCTURE. THE RELATION BETWEEN CREEP AND SHRINKAGE IS DISCUSSED. /LCPC/RRL/A/
