A simple one-dimensional numerical model using the enthalpy transforming scheme is developed to predict thermal responses of a fire wall made of an inorganic insulator for middle and high temperature ranges such as a calcium silicate board with crystalline water and physically absorbed water. The latent heat of crystalline water and absorbed water in calcium silicate boards were measured for the model by using a thermal analyzer of TG/DTA. Numerical computations to simulate the thermal responses in a standard fire resistance test were performed for a sand wall containing 5 vol% of moisture and two calcium silicate boards. Experiments using the sand wall and the calcium silicate boards were also performed. The numerical results were compared with the results of experiments. The proposed model accurately predicts the thermal responses of the wall.
