Abstract

The setting and hardening of concrete is accompanied by nonlinear temperature distribution caused by developing heat of cement hydration. expecially at early ages, nonlinear temperature distribution has a large influence n the crack evaluation. So the need to predict the exact temperature history in concrete has led to the examination thermal properties. In this study, the convection heat transfer coefficient is experimentally investigated which is one of the thermal properties in concrete. Furthermore, the result of the experiment is compared with those of analysis by the program which is developed in KAIST. As a result of comparison, the analytical results are in good approximation with experimental data.
