cold weather concrete


Is there a way of applying concrete in cold weather with temps around or 5 degrees below freezing. This is spot 3-4 inches deep and runs about 3 feet long, 10-12 inches wide.
I heard adding antifreeze to the water. I cannot apply a heat blanket applying a heat blanket over the work.

Though some masons may refer to additives used in cold weather as "anti-freeze" it is not actually anti-freeze and is not recommended to use this. The most common additive is Calcium chloride, even when using this you have to take extra steps to protect the work from extreme cold. Here is a page the covers some of the basics.

Even though this is for masonry work the same thing, would apply.
