Research findings in the past have demonstrated that the heat of hydration can induce thermal cracking in early age concrete. The disproportionate thermal expansion can cause considerable tensile stresses at concrete surfaces. The minimum size of mass concrete has remained unsolved due to the complexity of the problem. In this study, a way to predict early age concrete temperature and associated thermal stresses is described, including the needed experimental testing and finite element modeling technique.;In thermal analysis, an adiabatic calorimeter was designed and built to measure the adiabatic temperature rise of the concrete. The measured adiabatic temperature rise was converted into a mathematical formulation for finite element modeli...
