Which mortar is described as a dry mix of Portland cement, sand, and admixtures that controls the setting of the bed?

• A. Mortars and adhesive
• B. Cement mortar
• C. Dry set mortar
• D. Epoxy mortar

Answer: (C)

Dry set mortar is a dry blend of Portland cement, graded sand, and admixtures kept in a dry form until you mix it with water. Those additives tune the mix to set in a controlled, predictable way, giving you a stable bed for tile or stone and making it easier to position pieces before it hardens. That combination—a dry mix with Portland cement, sand, and admixtures that governs the setting—is exactly what this description describes. Epoxy mortar uses epoxy resin chemistry, not a Portland-cement-and-sand dry mix. Cement mortar is a broader term for standard cement-sand mixes that aren’t the specifically formulated dry-set type, and “mortar and adhesive” is a general category rather than a dry-set product. So the described mortar is dry set mortar.
