Tips for Curing Concrete in Cold Weather
The process of curing concrete becomes more challenging in cold weather since, to properly set and reach maximum strength, fresh concrete must be protected from freezing for at least the first 24 hours, or until it reaches a minimum strength of 500 pounds per square inch (psi). Concrete that freezes at an early age can lose much of its overall strength.

Concrete - Wikipedia
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...

Chemical Admixtures - Portland Cement Association
Retarders keep concrete workable during placement and delay the initial set of concrete. Most retarders also function as water reducers and may entrain some air in concrete. Accelerating admixtures increase the rate of early strength development, reduce the time required for proper curing and protection, and speed up the start of finishing operations.
