Concrete antifreeze is combined with winter application temperature conditions, which can accelerate the condensation and hardening of concrete under negative temperature conditions. The strength increases significantly and does not affect the development of later strength. It is free of chlorine salt to avoid Reduces corrosion of steel bars and improves durability of concrete.
1. Dosage:
Liquid: temperature -5 ~ -20℃ 2.0-5.0% of the cementing material
Powder: temperature -5 ~ -20℃, accounting for 2.0-5.0% of the cementing material
2. Function: Mainly used for commercial concrete, suitable for reinforced concrete, prestressed concrete and fly ash-mixed concrete.
How to use concrete antifreeze and precautions:
Concrete using concrete antifreeze Construction needs to be carried out in accordance with the relevant regulations on concrete construction in winter (you can refer to "Concrete Admixtures" (GB 8076-2008) and specific construction arrangements should be made in accordance with the regulations in "Concrete Antifreeze" (JC475).
General requirements: When the daily average outdoor temperature is stably below 5℃ for 5 consecutive days, winter construction begins. Antifreeze must be added. Antifreeze can be minus 5 degrees, minus 10 degrees, or minus 15 degrees).
