A HYPOTHESIS ON MECHANISM OF CREEP OF CONCRETE WITH REFERENCE TO MULTIAXIAL COMPRESSION

IT IS SUGGESTED THAT CREEP IS DUE TO ORIENTED INTERNAL MOISTURE DIFFUSION CAUSED BY A FREE ENERGY GRADIENT AND TO SLOW DEFORMATION OF THE ELASTIC SKELETON OF THE GEL INDUCED BY VISCOUS DEFORMATION OF ADSORBED WATER. SHRINKAGE ACTUALLY REALIZED IS AFFECTED BY THE RELIEF OF THE STRESS IN THE ELASTIC SKELETON BY CREEP. THE NATURE OF MOISTURE DIFFUSION SUGGESTS THAT CREEP STRAINS MAY NOT BE SUPERPOSABLE UNDER MULTIAXIAL STRESS. CREEP RECOVERY IS SHOWN TO DEPEND BOTH ON CREEP AT THE TIME OF UNLOADING AND ON MAGNITUDE OF ELASTIC STRAIN RECOVERY. A RHEOLOGICAL MODEL IS PROPOSED. SOME SUPPORTING EXPERIMENTAL DATA ARE PRESENTED. /AUTHOR/
