Are You Ready to Pour Concrete in Colder Temps?
As summer fades and we move into fall and winter, steps should be taken by contractors to ensure your cold weather projects are of the same quality as your spring and summer projects. Because of the colder temperatures and increased chance of precipitation, concrete may not set as quickly as you are used to. This in itself may be a problem, but there are tools available to help you manage your fall and winter projects.
Consider purchasing a concrete blanket to thaw ground before pouring and to protect concrete after the pour while it cures. Also, concrete blankets will allow you to avoid cracking and peeling in the winter by keeping the surface warm. They come in various sizes that can be utilized in a number of ways: to thaw sand, construction equipment, the ground, and walls.
Equipment intended for use during the entire year can also help cure concrete more evenly and efficiently. For instance, the use of a hot air lance can greatly reduce the time needed to cure cracks or seems in concrete. In winter particularly, the hot air lance can give the weakest places in your pour the strength they need to cure consistently. Take a look at our buying guides for more info and check out this video of a hot air lance in action:
Do you have any stats about the time that allows to gain using these blankets versus other curing conditions and achieving the same compression strenght on the concrete?
