Description

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.

Keywords: cement content; coarse aggregate; creep; formwork; heat of

hydration; mass concrete; modulus of elasticity; precooling; postcooling;

pozzolan; restraint; specific heat; strain; stress; temperature rise; tensile

strength; thermal conductivity; thermal diffusivity; thermal expansion; thermal

gradient; thermal shock.
