Heat transmission is obstructed until this slow process, known as calcination, is complete. During a fire, wood or steel structural members covered with gypsum panels are protected and the fire is contained because the temperature behind the panel is significantly lower than the temperature at which steel loses strength or wood ignites.
When gypsum is heated, it undergoes a process called calcination, during which it loses some or all of its water content, depending on the temperature and duration of heating. This results in the formation of different gypsum products with varying properties, such as plaster of Paris, stucco, and gypsum board. ... Complete Dehydration: If ...
