Question

Quizplus · Accepted Answer

Gypsum is primarily used in the construction industry to make plaster and wallboard. It is also used as a soil conditioner to improve soil structure and reduce soil compaction, but it is not normally spread directly on soils as a fertilizer. It is not used to extract the metal Ca, and although it is sometimes added to cement to slow down the setting time of the mixture, it is not the primary ingredient in cement production.
