May 06, 2018· Gypsum, also called Calcium sulphate dihydrate has a chemical formula of CaSO4 . 2H2O.. when it its heated at 373K it loses 3/2 of its water to give POP (Plaster of Paris) which is CaSO4. 1/2 H20.. HOPE THIS HELPS!
Iron oxide: Chemical formula is Fe 2 O 3. Iron oxide imparts color to cement. It acts as a flux. At a very high temperature, it imparts into the chemical reaction with calcium and aluminum to form tricalcium alumino-ferrite. Tricalcium alumino-ferrite imparts hardness and strength to cement. Calcium Sulfate: Chemical formula is CaSO 4
Gypsum as such is and eternally recyclable. You can always reuse Gypsum because the chemical composition of the raw material in plasterboards and blocks always remains the same. Gypsum is definitely a construction material with multiple environmental benefits!
Gypsum is a very soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It can be used as a fertilizer, is the main constituent in many forms of plaster and is widely mined. Mineral gypsum is the most common of the naturally occurring sulphate minerals.

Gypsum is the common name for the mineral calcium sulfate, which has a chemical formula CaSO 4.Gypsum bonds easily with water and is usually found in its natural state as hydrated calcium sulfate, with a chemical formula of CaSO 4.2H 2 0. Gypsum is a soft mineral that usually appears white or gray and is composed of translucent crystals.
Anhydrite is also found in the cap rock of salt domes and in cavities of trap rock. Anhydrite is an anhydrous calcium sulfate with a composition of CaSO 4. It is closely related to gypsum, which has a chemical composition of CaSO 4. 2H 2 O. The worldwide abundance of gypsum greatly exceeds the abundance of anhydrite.
3.6 Mineral and oxide composition of portland cement. When considering the composition of a portland cement, the most important factors are the relative amounts of each of the cement minerals, the amount of calcium sulfate, and the total amount of alkalis (Na and K).

Gypsum crystals are known for their flexibility, and slim crystals can be slightly bent. (Though trying to bend good crystals is not recommended, as their flexibility is weak, and if flexed too much they will break.) Gypsum has the same chemical composition as the mineral Anhydrite, but contains water in its structure, which Anhydrite lacks ...
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.
