This study was made to present a method for nonlinear coupling analysis of heat conduction and temperature-dependent hydration of cement and to indicate the difference of analytical results between the conventional linear method by using an adiabatic temperature rise curve and the proposed nonlinear method by using the temperature dependent heat hydration model. For the cement hydration model, the heat generation rate depending on the temperature and past hydration process was adopted as a function of temperature and accumulated heat.
This nonlinear analysis results are considerably different from that of the conventional linear analysis in case of thin wall type structure. The proposed nonlinear analysis is able to express the actual behavior occurred in the concrete structure with high fidelity.
