Experiment Method on the Heat Transfer Coefficient in Air Convection of Young Concrete

Abstract:

Along the process of setting and hardening in concrete, the temperature profile shows gradually a nonlinear distribution due to the development of hydration heat of cement. More specifically, at early ages of concrete structures, this nonlinear distribution has a large influence on the crack evolution. As a result, to obtain the exact temperature history, it is necessary to examine thermal properties of the concrete. In this study, the convective heat transfer coefficient, which presents heat transfer between concrete surface and air ambient, was experimentally investigated with test variables such as velocity of wind, type of form, and water-cement ratio.
