Assuming constant water content, linear stress range, and temperatures between 2 degree C and 80 degree C-100 degree C, creep of aging concrete at normal and elevated varying (or constant) temperatures, a phenomenon of importance for nuclear reactor vessels, is formulated by a rate-type creep law with hidden stresses based on Maxwell chain model of time-variable properties. Introducing the equivalent hydration period, acceleration of aging due to temperature rise is formulated by means of the activation energy of hydration.
