Popis:	We investigated hydration and strength development of cementitious materials cured under freezing or drying condition experimentally. The test results show that hydration and strength development depend on both temperature and chemical potential of water. Theoretical study makes it clear that effect of temperature follows the Arrhenius equation and the activation energy in the equation is proportional to the decrease of chemical potential. Consequently the equivalent maturity method that describes the rate of hydration under drying and freezing condition was proposed.
