Why Is Concrete Cooling Necessary?

The temperature of concrete is most significantly affected by the water used in the hydration process Thus concrete cooling methods often involve cooling the mixing water prior to hydration However the temperature of the cement aggregates is also important and by pre-cooling the aggregates lower hydration temperatures can also be achieved
