Gypsum Mineral Uses and Properties

Gypsum Mineral Uses And Properties

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

Salinity amendments Salinity Management

Salinity Amendments Salinity Management

Gypsum added to a sodic soil increases the soil water EC and reduces SAR (or ESP), thus improves soil permeability. Gypsum application rate depends on the amount of initial exchangeable Na fraction in the rootzone (Na ie ), soil cation exchange capacity (CEC, mmol/Mg), soil bulk density (BD, Mg/m 3 ) and the final exchangeable Na fraction (Na fe ).

Gypsum An Old Product With A New Use Integrated

Gypsum is used to add large amounts Ca 2 ions that displace the Na ions from the exchange sites, and when flushed with clean water both salts and Na are removed from the soil (gypsum is used instead of limestone because of higher solubility and no increase in soil pH). However, even in these sites this practice is not effective when subsoils have low permeability to water.

Gypsum, unlike cement, is a physical structure rather than a chemical structure. The needle-like gypsum crystals form a network to give the board its physical integrity The crystals are closely interwoven, giving the core most of its wet strength. After drying, the frictional forces of these crystals increase the strength of the core.
