Pouring concrete presents a plethora of difficult challenges, and when cold weather comes into the mix, things get even more complicated. This is because concrete needs to dry and develop properly in order to maintain safe levels of strength and integrity, which means it needs to be protected from freezing shortly after pouring. But pouring concrete in cold weather is entirely possible, and Steel Guard Safety’s concrete blankets can help.
According to the American Concrete Institute, concrete is exposed to cold weather conditions whenever the average daily temperature is below 5ºC (40ºF) and the air temperature doesn’t rise above 10ºC (50ºF) for more than half of any 24-hour period. In these conditions, the concrete may be in danger of freezing and the cold weather can interfere with the setting and curing process. If local weather trends indicate you might be facing these conditions as you pour or manage the concrete, you should plan to take precautions against cold weather.
There are a variety of methods available to keep concrete at a sufficient temperature, but concrete blankets are one of the simplest and most effective. These insulated thermal tarps can be used as concrete curing blankets, temporary curtain walls, or temporary heat enclosure, making them a versatile tool for creating the proper temperature environment for curing concrete. No matter how they’re used, it’s critical to diligently measure and record the temperature of the concrete to ensure it never dips below the required target.
As always, it’s important to consider the specific challenges of the job at hand when planning to pour concrete in cold weather. If there are specific strength requirements for the concrete, make sure you’re keeping the concrete at temperatures that will allow it to meet those requirements. Also remember to never pour concrete on ice, snow, or frozen ground – if the ground freezes, you’ll need to heat and thaw it before pouring the concrete.
