Gypsum moisture varies depending on the source of its deposit (, sea water, volcanic vapors, industrial byproduct, etc.) and the requirement of its final application or product (, agricultural soil amendment, gypsum wall board, concrete, etc.).
There are five common types of gypsumfinish coat plasters. Readymix gypsumfinish plasters are designed for use over gypsumplaster base coats. They consist of finely ground calcined gypsum, some with aggregate and others without. On the job, just add water. Gypsum acoustical plasters are designed to reduce sound reverberation.
The clinker and gypsum are then interground, producing the superfine powder called portland cement. Gypsum is a critical ingredient that helps to control the setting time of the cement when it is mixed into concrete. Without gypsum, the cement would begin to set immediately.
Marine gypsum are normally recovered from salt pans during the production of salt, mainly from Gujarat and Tamil Nadu. Marine gypsum production is in a very negligible quantity, around mtpa, and expected to remain negligible in the long term.

Abstract. Sulfate attack on Portland cement concrete is often said to arise from each of two major sulfate reactions: (1) The sulfate ions react with C{sub 3}A and its hydration products to form ettringite with an increase in volume that results in expansion and subsequent cracking of the concrete; (2) The sulfate ions react with calcium hydroxide (CH) to form gypsum.

The main cost incurred in the production of concrete paving blocks is the cost of the cementbased binders. In addition, there is the environmental cost of quarrying and processing of these primary materials. Gypsumbased industrial byproducts have been identified as alternative sources of cement. These materials have little or no production cost and their reuse negates the need for disposal ...
The production of plaster of Paris is mainly from gypsum. However, there are few differences between gypsum and plaster of Paris. Among them, the key difference between gypsum and plaster of Paris is that the gypsum contains calcium sulfate dihydrate whereas the .

Gypsum is an essential additive, as it acts as a set regulator for the cement. Other additives that are commonly used in small quantities are fly ash and limestone powder. Control of temperature is essential during grinding, since high temperatures during intergrinding could cause a transformation of gypsum into hemihydrate or anhydrite, which ...
