Early-strength antifreeze is different from early-strength agent. Early-strength agent only needs to consider improving the early strength of concrete, while early-strength antifreeze needs to comprehensively consider how to improve the early strength of concrete. , so that the concrete reaches the critical strength as soon as possible to reduce the possibility of freezing damage. In addition to improving the early strength, early-strength antifreeze also needs to reduce water to reduce the water-cement ratio, and appropriately entrain air to reduce the internal causes of frost heave damage. When preparing early-strength antifreeze, you don't need to add too many antifreeze components. Try to reduce the amount of antifreeze. It is not only economical and cost-effective, but also good for the durability of concrete.
Early-strength antifreeze is suitable for low-temperature early-strength concrete construction where the minimum temperature is not less than -10℃. Early-strength antifreeze is mainly composed of early-strength and antifreeze components. It can also be appropriately compounded with a small amount of water-reducing and air-entraining components according to construction needs. The dosage should not exceed 5% of the cement mass.
