Summary
A method based on the rate theory is developed to discribe the total compressive creep deformation, by introducing a relation between the true activation free energy and the time: \(\exp \left\{ {\left( {\text{Q - Q}_\text{0} } \right)/\text{kT}} \right\} = \left( {1 + \text{t/d}} \right)^\text{m}\). Several concrete specimens were tested under normal load as well as under high compressive load. It was possible to fit primary-secondary-tertiary creep curves with a correlation coefficient better than 0.9977.
