what is ideal temp to pour concrete
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 â¥ 40ÂºF. Anything below this will slow the hydration process, and may even stop it altogether. It is critical that the concrete sets before it is exposed to freezing temperatures.
