Aug 29, 2020· "Harrison Gypsum expanded into the plaster and cement industry with the addition of Allied Custom Gypsum (ACG) in 2001," said Madsen. "There are now 23 active mines and four manufacturing plants in the United States, including in Oklahoma (gypsum and limestone), Texas (gypsum), Kansas (limestone) Nevada (anhydrate gypsum), and Washington (limestone).
Compensating for this loss by increasing the clinker content in the cement would be counterproductive because it would increase the CO 2 emissions of the cement industry. Instead, new additives have to be found. Research in this sector focuses on materials such as limestone.

Cement, lime and gypsum manufacturing processes have in common the mixing of inorganic minerals calcined at high temperatures, typically ... and partially fuses the ingredients into lumps known as clinkers. These clinkers are then cooled and pulverized into fine powder. Some gypsum is used to control the speed of setting
Historically gypsum has generally tended to be used as an additive to lime. The speed at which a mix of lime and gypsum set (which is slightly slower than gypsum on its own) and the slight expansion that occurs, are particularly useful when running cornices and other mouldings in-situ.
Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
