Abstract:
The need for the control of temperature-induced stresses during the hydration period in mass concrete work has long been recognized. The recent development and widespread use of high-strength concrete mixes having high cementing materials contents warrants further research in this regard. This paper describes procedures incorporated in the construction of massive high-strength, reinforced concrete transfer girders in a recent Toronto high-rise project. Following initial testing, control specifications were revised to permit thermal gradients beyond traditionally accepted limits.
