A parametric study regarding the physical properties of the gypsum is carried out. The predictions obtained with the in-house developed code are in good agreement with experimental data, when temperature dependent physical properties are taken into account. The good performance of gypsum boards under fire conditions, from the fire safety point of view, due to the dehydration/calcination process and the occurring energy absorption is pointed out by the numerical results.6 pagesPDFenUniversity of PretoriaHeat transferGypsum plasterboardsNumerical codeSimulationDehydration processCalcination processOne dimensional heat transferPresentation
