How hot does concrete get during curing? How Much Heat Is Generated By Curing Concrete? In general, for every 100 pounds of cement used, concrete gains anywhere from 10 to 15 degrees Fahrenheit during curing. Controlling the temperature of concrete as it cures is very important to insure that it cures over a long enough period of time.
Does concrete give off heat when curing? The heat produced by concrete during curing is called heat of hydration. This exothermic reaction occurs when water and cement react. The amount of heat produced during the reaction is largely related to the composition (Table 1) and fineness of the cement.
How long does new concrete generate heat? Cement hydration is a chemical reaction. The rate at which that reaction takes place is dependent on temperature. But also, because the reaction is exothermic, concrete generates its own heat during hydration–over the first two or three days.
