ACI 207.4R-05: Cooling and Insulating Systems for Mass Concrete (Reapproved 2012)

The need to control volume change induced primarily by temperature change in mass concrete often requires cooling and insulating systems. This report reviews precooling, postcooling, and insulating systems. A simplified method for computing the temperature of freshly mixed concrete cooled by various systems is also presented.
