1. Introduction. The cement manufacturing industry is the major consumer of gypsum, which is added to the clinker in a percentage of 35 wt , , . Various byproduct gypsum such as phosphor, fluoro, citro, boro, titano, tartare, and desulphogypsum have chemical composition similar to the natural gypsum, but its use in replacing natural gypsum as cement retarder is limited, mainly due
Read MoreThe term 34synthetic gypsum34 has been used widely to encompass materials produced by a variety of industrial processes. In addition to FGD gypsum, synthetic gypsum includes materials such as phosphogypsum, a byproduct of processing phosphate ore to make phosphoric acid, Titanogypsum a byproduct from the production of titanium dioxide, fluorogypsum a byproduct from the production of
Read MoreThe reports conclusion states EPA supports the beneficial use of coal fly ash in concrete and FGD gypsum in wallboard. The Agency believes these beneficial uses provide significant opportunities to advance Sustainable Materials Management SMM. The EPA final report on FGD gypsum can be found here.
Read MoreWith flue gas desulfurization gypsum addition, as much as 55 reduction in CO 2 intensity of concrete production can be achieved with no loss in concrete strength. The synergetic use of flue gas desulfurization gypsum and slag makes concrete production much cleaner while turning both types of industrial solid wastes into valuable resources.
