Cold Weather Concrete Placement- How to Protect and Cure ...

Cure concrete in cold weather without additional water; adding water will keep the concrete saturated so that freezing will damage it even after it reaches 500 psi compressive strength. Concrete in cold weather absolutely does need to be cured-the surface can dry out even faster than in warm weather, if the concrete is warmer than the air.
