Abstract:
Shrinkage and creep under different stresses were studied on several specimens of concrete. Once analyzed and discussed, the experimental results reveal to two classes of distinct phenomena: at high temperatures, the concrete, freed of its evaporable water, would appear to behave according to the classical Arrhenius equation during changes in state; for lower temperatures, pure creep due to temperature would be very slight, shrinkage and shrinkage under loading would vary with the steam pressures bringng about the desorption of evaporable water.
