Flash Set and False Set Concrete Construction Magazine
If inadequate amounts of gypsum are added to the cement, flash set can occura rapid development of rigidity in freshly mixed portland cement paste, mortar, or concrete. Further mixing can''t dispel this rigidity, and a large amount of heat is produced in the process. Rapid development of rigidity can also be caused by false set. But in this

Cement kiln Wikipedia
Plants that burn waste fuels enjoy a negative fuel cost (they are paid by industries needing to dispose of materials that have energy content and can be safely disposed of in the cement kiln thanks to its high temperatures and longer retention times). As a result, the inefficiency of the wet process is an advantage—to the manufacturer.
