Did you know that although concrete placed in cold temperatures may need longer to cure, the final strength could be higher than concrete cured at warmer temperatures?  That is about the only benefit to placing concrete during the colder temperatures.  This winter keep these tips in mind in order to maintain the quality of your concrete:

1. The temperature difference between concrete and the subgrade should be no more than 30°F.  Do not place concrete on a frozen subgrade.
2. Edges and corners should receive extra protection because they are exposed to heat loss in multiple directions.
3. The most important time period for a concrete pour or placement is the first 24 hours.  During this initial time the concrete needs to be prevented from freezing until it achieves its initial strength of 500 psi. 
4. The best method for keeping the concrete from freezing is to insulate it with foamed vinyl curing blankets, polystyrene foam sheets, or straw.

From now until the end of the year, The Concrete Store’s curing blankets are on sale.  Contact the store at 888-233-0477.
