Abstract

This chapter reviews the complex market of gypsum-based products. It begins with definitions, according to ASTM, EN, and ISO standards, of the most common products such as gypsum plaster or gypsum plasterboard. The next heading establishes the two main sources of raw materials for manufacturing gypsum products: natural and synthetic gypsum, e.g., flue-gas-desulfurization (FGD) gypsum. Moreover, the different geological occurrences of gypsum are summarized. Gypsum plaster manufacturing process as well as the main properties of gypsum and gypsum products (fire, acoustic, thermal, and other properties) are described. Gypsum products and applications are taken into account in the last heading of the chapter, including items specifically devoted to plaster and plasterboard. For every product, main characteristics as well as the manufacturing processes are discussed. Other important gypsum-based products such as glass fiber reinforced gypsum, gypsum blocks, or gypsum tiles are also considered.
