Gypsum Board an overview ScienceDirect Topics

Gypsum boards or plasterboards are typical materials used to build light walls. The production process is based on gypsum hydration technology. At the very beginning of the process dehydrated calcium sulfate (gypsum) is converted into CaSO 4 ·0.5H 2 O by heating. Once dehydrated, gypsum is mixed with water, starch, a foaming agent, and other additives.

Gypsum-board face paper is commonly 100 percent recycled from newsprint, cardboard, and other postconsumer waste streams, but most recycled gypsum in wall-board products is postindustrial, made from gypsum-board manufacture. Gypsum board should be purchased in sizes that minimize the need for trimming (saving time and waste).

Gypsum Plasterboard and the environment

Plasterboard production 'Stucco' is produced by removing around 75% of the water from the gypsum through heating using natural gas to a temperature of over 150'C. This process of 'calcination' changes calcium sulphate from its dihydrate state (gypsum) to its hemihydrate state.
