A study on the strength development under freezing condition and the freezing behavior of water in concrete with and without accerelatores for freeze protection was carried out. The concrete contained accerelatores for freeze protection cured at 20°C have shown strength gain in both short and long term superiority over AE ordinary concrete. At the same maturity, the strength of the specimens which contained accerelatores for freeze protection higher than standard dosage cured under freezing conditions was even higher than that of AE ordinary concrete specimens cured at 20°C. Strength development under freezing condition was influenced by the amount of unfrozen water in concrete. Freezing behavior and self-drying were measured by means of a method to estimate moisture contents as a function of resistivity and temperature. Unfrozen water in concrete was increased by using accerelatores for freeze protection. The strength of concrete using accerelatores for freeze protection to prevent the frost damage at early ages would be lower than that of AE ordinary concrete.
