영문 초록

Concrete and mortar can be damaged by frost when they are exposed to low temperatures at early ages, and the strength development can be delayed. To prevent an early frost damage, a chemical accelerator for freezing resistance that can reduce the freezing temperature of concrete or mortar is used. In this study, the preventive effect of salt-free and alkali-accelerator for freezing resistance on early frost damage was evaluated. Three types of accelerators for freezing resistance were used in this experiment. Accelerators for freezing resistance of 2ℓ, 4ℓ, and 6ℓ per 100kg cement were used in mortar, and the freezing temperature of mortar was measured. Consequently, mortar that used accelerators for freezing resistance of S Corp, B Corp, and K Corp showed the freezing temperature range of -0.3 to -1.8°C, -0.7 to -1.9°C, and -0.9 to -3.7°C, respectively. Therefore, these accelerators for freezing resistance can be used in slight frost conditions but not in air temperature conditions of below-10°C.
