What happens to freshly poured concrete in rapidly plunging temperatures? Let’s investigate. First, if you have to pour in the middle of winter, you will have cracking and scaling, unless you take precautions to insulate the concrete as it dries, hardens, and settles. One source states that four days after a pour in 20 degrees Fahrenheit, having dried under and insulating blanket, the temperature beneath the blanket was 70 degrees. It’s especially important to have a professional with experience working in extreme temps, like the folks at Wright Construction, if you are planning on pouring in the middle of winter. However, even if you have help from a trusted professional, it never hurts to know a few things about the situation at hand.
Did you know:
If concrete freezes before it dries, it will be potentially 50% less strong and susceptible to fissure.
As temperatures drop, so does the rate of surface hydration; lack of surface hydration can affect the overall strength of concrete.
Wet concrete, itself, produces heat, and this heat plus the heat produced by insulation, should be enough to allow your concrete to cure.
These are just a few considerations when it comes to concrete in winter. The friendly professionals at Wright Construction are sure to have the answers for questions you might have about ensuring the strength of your concrete when poured in winter.
