Which term refers to the mixture of Portland cement and sand used as a bonding mortar in tile installations?

Explanation:
The bonding layer for tile is a cementitious mix of Portland cement and sand, which is known as cement mortar. This combination creates a strong, cohesive bed that bonds the tile to the substrate and distributes loads. Grout, in contrast, fills the gaps between tiles after they’re set, not the bonding layer. Dry-set mortar is a specific type of cementitious bonding mortar, but the general term for the Portland cement–sand mixture used to bond tiles is cement mortar.
