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