Field of Application
Performing concrete in cold weather for temperatures ranging from -15 to +5° C,
When freezing or quick temperature drop is forecasted.
Properties and Effects
Increasing concrete setting and hardening,
Intensifying heat generating and attaining higher resistance to freezing at early ages,
lowering freezing point of water content in concrete,
Decreasing water-cement ratio under constant workability condition,
Increasing integrity and durability of concrete in freezing condition,
Increasing the speed of hydration process and heat generating,
According to the ambient temperature and the cement percentage, the dosage rate varies. Paying attention to the requirements of cold weather concreting, table 1 can be used as a reference.
Instruction for use
BC37 should be added by mixing water or after, then continue mixing.
Physical state: Liquid
Solubility: In water
Storage: In capped container protected against air,
Shelf life: 1 year in original package,
Packaging: 25 and 250 Kg drums.
Technical observation and application
The cold weather is referring to condition where the average ambient temperature for more than three continuous days is less than +5°C. If the ambient temperature in more than half of a 24
hours period is above +10°C, it isn’t verifying to cold weather concreting anymore,
Obeying the requirements of ACI 306R code for concreting in cold weather condition is necessary,
Table 2 is a good reference for concreting in cold weather,
When simultaneous use of several admixtures in concrete mix is required, consult Research Center of Beton Chimie.
