Avoid These Concreting Cold Weather Mistakes

Amzeal News/10514034
ATLANTA - Amzeal -- With record cold temperatures sweeping across the United States this winter, cold temperature is at the forefront of most people's minds.

As a building owner or property manager, you've likely been thinking about how the weather will be affecting your properties.

If you're in the middle of a construction or repair project, cold weather can grind any work to a complete halt. However, once you know the challenges of cold weather concreting, you can take steps to account for them.

According to Whitecap.com, "The American Concrete Institute (ACI) defines cold weather concreting as "a period when the ambient temperature is below 40°F (5°C) for three days or more." The temperature is calculated as an average of the highest and lowest temperature from midnight to midnight."

What can you do to make sure your concrete work is worth the time you spend on the project? Knowing how to handle cold weather conditions will ensure your project doesn't face costly setbacks.

We recommend adjusting the mix design to offset the impact of cold weather. Use type III cement (its finer, reacting faster to speed up the hydration process), where strength losses from ice crystals can be counteracted.

Additionally, consider accelerating admixtures which speed up the drying/hydrating process to counteract the impact of the weather. Calcium chloride, sodium nitrate, and calcium nitrate are good options (though calcium chloride shouldn't be used in reinforced concrete). We also recommend keeping the concrete mix warm with heaters and blankets.
