Numerical simulation of hardening of concrete plate
The paper presents a theoretical formulation of concrete curing in order to predict temperature evolution and strength development. The model of heat flow is based on a well-known Fourier equation. The numerical solution is implemented by means of the Finite Difference Method. In order to verify the model, the in situ temperature measurements at the top plate of a road bridge were carried out. A high agreement between numerical and experimental data has been achieved. The results allowed to perform extended analysis of boundary conditions changes on the process of heat flow in the concrete slab. Three examples of the boundary conditions are presented and discussed.
