Paragraph Number

5

In addition, it is important to properly cure the concrete for strength once it has been poured. Typically the concrete must cure for about seven days at a temperature within the range of 50 degrees Fahrenheit to 90 degrees Fahrenheit, with 70 degrees Fahrenheit as the optimum temperature. If concrete cures in temperatures below 50 degrees Fahrenheit, the strength and durability of the concrete is greatly reduced. In an outdoor environment where freezing temperatures exist or may exist, it is difficult to maintain adequate curing temperatures.
