Fire-Resistance Property of Cement Extruding Panel Mixed with Alpha-Hemihydrate Gypsum

초록
Gypsum is an important building material used to provide fire resistance to constructions by reducing their temperature rises. As the hardened gypsum is exposed to fire, evaporation of both the free water and the chemical bond water is easier than that in the cement extruding panel. The purpose of this study is to investigate the utilizability of alpha-hemihydrate gypsum to prevent spalling failure of cement extruding panel exposed to fire. This paper reports the fire-resistance property of a controled general cement extruding panel(C100), and gypsum-cement extruding panels(C50A50, A100) according to replacement ratio of alpha-hemihydrate gypsum. As a results, it is found that A100 and C50A50 are more effective to prevent the explosive spalling failure under standard fire condition than C100.
