    A numerical simulation model is presented to predict drying of concrete slabs of certain Finnish concrete grades. The coupled equations of heat and moisture transport in porous materials including the hydration phenomenon are incorporated in the model. The simulation model and its parameters were calibrated according to long-term measurements that were performed in a laboratory for test pieces of different concrete grades. As the material properties for quantities governing moisture transport were insufficient, parameters of the functions describing the material properties were fitted to the experimental data by employing the optimization analysis coupled to the simulation. A reasonable agreement was found and the unknown material parameters were solved, the values of which can be used in further simulations of real concrete structures.
