Description	The effect of high temperatures on heat and moisture transport in porous materials is studied. Transport processes are simulated on a fiber reinforced cement composite using Lykov's original model. The main objective of the simulation is to determine limits of two parameters which are difficult to measure - relative thermodiffusion coefficient δ and evaporation coefficient ε. In order to specify influence of those two on temperature and moisture fields in material, a sensitivity analysis under specific conditions is performed. Further, the original model is modified by introducing dependence of ε on temperature. Then δ is examined by varying between its estimated possible limits. Finally, the influence of two studied parameters is quantified and compared with experimental data. The effect of high temperatures on heat and moisture transport in porous materials is studied.
