Gypsum board is a building material that shrinks and cracks at high temperatures, which compromises the structural integrity of buildings during fires. Researchers in this study set out to determine the behavior of gypsum board when exposed to real fire conditions. A Thermal Constants Analyzer (TPS) measured the thermal conductivity of the gypsum board samples at and above room temperature using the transient plane source (TPS) technique. Results showed that ...
Phase change materials (PCMs) store large amounts of latent heat over small temperature ranges, so their application in the thermal regulation of buildings is becoming more popular. However, PCMs have low thermal conductivities, so micro-encapsulated PCMs (micro-PCMs) are being incorporated into PCMs to enhance their performance and improve thermal conductivity. In this study, micro-PCMs were mixed with thermally conductive, inorganic gypsum powder and glass fiber to produce gypsum boards. The ...
The thermal conductivities of 6 rocks containing gypsum, as well as 6 rocks in which gypsum is absent were determined experimentally. The rock samples were taken from the Kuqa depression, in the north of the Tarim Basin, China. It was determined that gypsum-bearing rocks are thermal insulators, and this property when combined with other properties of gypsum-bearing rocks make them good cap rocks and also make them suitable for oil production and ...
