Which of these is NOT a type of cement typically used in construction?

Gypsum cement is not recognized as a type of cement typically used in construction. The primary types of cement used in the industry include Portland cement, known for its strength and versatility in various construction applications; high alumina cement, which is valued for its rapid strength gain and resistance to hydraulic environments; and composite cement, which is a blend designed for specific performance characteristics.

While gypsum does play a role in construction materials (for example, in drywall and plaster products), it does not qualify as a standalone cement type for structural applications like the others mentioned. Each of the other types serves distinct purposes in construction, with Portland cement being the most widely used globally due to its effective binding properties.
