Present theory of frost action in cement is re-examined in the light of the results of recent experiments (dimensional changes, adsorption characteristics, calorimetry, DTA). It is found that hydrostatic pressure in cement is not generated by the 9 per cent difference between the specific volume of water and ice but by the changed interaction between the cement and the adsorbed water on its solidification. The proposed mechanism raises the possibility that new methods for frost protection may be developed. Similarly, frost susceptibility may be tested in a more reliable way.L'auteur examine la th\ue9orie accept\ue9e de l'action du gel dans le ciment \ue0 la lumi\ue8re des r\ue9sultats d'exp\ue9riences r\ue9centes, par d\ue9termination des c...
