Which term refers to the factors that determine the tile's resistance to traffic, including base and bonding material rigidity, grout strength, hardness, and proper leveling and smoothness?

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

Answer: (B)

The factors that determine how well a tile stands up to traffic come from the installation system—the way the tile is affixed and finished, including how the base and bonding materials behave, how strong the grout is, and how level and smooth the surface is. Mortars and adhesive describe that entire system, covering the setting mortars or adhesives used to bond the tile and the grout that completes the joints. When this system has good rigidity, strong bonding, proper leveling, and a smooth, even surface, the tile resists traffic-induced movement and wear much better. The other options refer to individual materials or wear processes rather than the whole installation system that governs these performance traits, so they don’t fit as well.
