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.
