Using a combination of transient plane source (TPS) technique and slug calorimetry, 4 commercially available fire resistive materials (FRMs) are studied from room temperature to 1000°C. The materials studied in this report are two gypsum-based and two calcium-silicate based materials. These materials are heterogeneous and thus when heated to elevated temperatures, the microstructure of the materials may be compromised and various reactions and phase changes may take place over the course ...
