A gypsum board is a panel made of gypsum plaster pressed between two thick sheets of paper. It is used to make interior walls and ceilings because it is produced from compact gypsum mineral powder which is very fragile. A few similarities between Gypsum board and Fiber Cement Board are that they are good insulators, fire-resistant, and nontoxic.

Gypsum is added to cement to regulate the setting reaction that occurs when cement mixes with water. It slows the reaction between tricalcium aluminate (C3A) and water, which would otherwise cause flash setting. When gypsum dissolves in water, it reacts with C3A to form ettringite, coating the C3A particles and allowing the cement mixture to remain workable. …
