Gypsum: Types, Properties, Advantages Disadvantages

Introduction to Gypsum: The word gypsum is derived from a Greek word meaning ‘to cook’ known as a burnt or calcined mineral. Gypsum is extensively used as a construction material; it contains 70% of CaSO4, 2H20 can be used for building construction. Chemically, gypsum is a sulfate of calcium with two molecules of water i.e. CaSO4, 2H20.

Gypsum is a type of soft sulfate mineral known for its usefulness in day-to-day lives. It is also referred to as calcium sulfate dihydrate. It consists of water, calcium sulfate and oxygen molecules and is chemically represented by the formula CaSO 4.2H 2 O. An evaporite mineral, gypsum is mostly found in layers of sedimentary rocks on the earth’s crust along with other minerals such as ...

Gypsum - an overview ScienceDirect Topics

G. Cressey, in Encyclopedia of Geology, 2005 Introduction. Gypsum (CaSO 4 2H 2 O), the most common of the sulphate minerals, is also known as alabaster (a fine-grained massive form), satin spar (a fibrous variety of gypsum), or selenite (colourless transparent gypsum crystals). Gypsum is often found in considerable thicknesses within evaporite sequences and in association with limestones ...

Halite and gypsum are called evaporite minerals, because they precipitate as water evaporates in coastal bays or desert dry lakes. Halite is none other than common table salt, and has cubic cleavage. Gypsum has platy cleavage, and is softer than a fingernail.

Gypsum. Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers. It forms in lagoons where ocean waters high in calcium and ...
