What is the primary reason for using mortar in construction?

The primary reason for using mortar in construction is to bind materials together. Mortar serves as a critical adhesive that holds various building materials, such as bricks, stones, and masonry units, securely in place. Its composition usually includes a mix of cement, sand, and water, which allows it to set and harden over time, creating a strong bond that maintains the structural integrity of walls and other construction elements. This binding property is essential for the stability and durability of structures, ensuring that they can withstand various forces and loads.

While aesthetic appeal, insulation, and weather resistance can be secondary benefits associated with mortar use, they do not represent the core purpose of its application in construction. Mortar is primarily recognized for its role in secure assembly rather than as an insulator or a decorative element.
