What is the primary role of mortar in masonry?

• A. Bonds Masonry Units Together
• B. Provides Waterproofing
• C. Adds Thermal Insulation
• D. Acts As Decorative Finish

Answer: (A)

Mortar’s main job is to bond masonry units together, creating a continuous, load-distributing wall. The paste fills the joints between bricks or stones, lets units align, and holds them in place so the wall behaves as a single structure. It also cushions irregularities and accommodates slight movements, helping transfer loads and resist wind and gravity. Waterproofing, thermal insulation, and decorative finish are secondary aspects influenced by the overall wall design and finishes; mortar by itself mainly provides the adhesive and gap-filling function that holds the masonry together.
