    Jan 13, 2019· Curing concrete in cold weather will produce a slower curing procedure, so the concrete is setting slowly, and bleeding will also start later than expected. Be prepared to handle more bleed water than regular concrete placement. While concrete is being cured, verify the concrete temperature using an infrared temperature gun.

    Pouring Concrete in Cold Weather – Yes, it Can Be Done!

    Curing is one of the most important steps in concrete construction. Proper curing greatly increases concrete strength and durability. Concrete sets much slower in cold weather. In order for hydration to occur, the temperature of the concrete must be ≥ 40ºF. Anything below this will slow the hydration process, and may even stop it altogether.


    The time it takes the autoclave to come up to curing temperature will vary with the size. It may require 5 to 10 minutes for a small unit or 60 to 90 minutes for a large unit to reach the specified cure temperature. The same is true for the cool down. Some only have air for cooling others may have water-cooling.
