What is 'bond beam' in masonry?

1. A decorative element installed between bricks

2. A reinforced concrete beam placed at the top of a wall for stability

3. The joint between two bricks

4. A type of adhesive used in masonry

The correct answer is: A reinforced concrete beam placed at the top of a wall for stability

The term 'bond beam' refers to a reinforced concrete beam that is typically placed at the top of a masonry wall to enhance the structural stability of the wall. It serves various purposes, such as distributing loads from the roof or upper floors and ensuring that the masonry remains intact during seismic activities or heavy wind loads. By reinforcing the wall at its top, bond beams help tie the structure together, preventing failure due to lateral forces or movement. In masonry construction, bond beams are essential for maintaining the integrity and durability of the structure, especially when dealing with taller walls or those subjected to significant stress. The inclusion of reinforcement, such as steel rebar, provides additional strength and supports the weight of the materials above. Understanding the role of bond beams is critical for bricklayers and those involved in masonry construction, as they contribute to the safety and performance of the entire building.
