An improved law of creep of concrete at constant humidity and temperature is proposed. The well-known double power law gives too high a final slope of creep curves compared to available test data. This is remedied by a new formula which exhibits a continuous transition from a power curve to a straight line in the logarithm of creep duration. The straight line has the same slope for all ages at loading, and the higher the age at loading, the longer is the duration at which the transition occurs. The exponent of the initial power curve is higher than that used in the double power law and is much too high in comparison with the existing test results for very short load durations in the dynamic range.
