1.10 : 砖石砌体中的砂浆接缝

Mortar joints are the spaces between bricks filled with mortar. Joints bind the bricks together, ensuring structural integrity and strength.

The thickness of these joints can vary, ranging from less than a quarter-inch to more than a half inch, depending on the application and structural requirements.

Joint tooling is a process applied once the mortar begins to harden; it involves compacting and shaping the mortar to improve the brickwork's overall appearance and resistance to weather conditions.

Various joint profiles exist, like the concave, vee, raked, stripped, flush, ruled, and rodded joints, each offering distinct aesthetic appeal and functionality.

For instance, concave and vee joints are well-suited for outdoor applications due to their excellent water-shedding and resistance to freeze-thaw cycles.

On the other hand, raked and stripped joints are ideal for interior brickwork.

Flush, ruled, and rodded joints work for interior as well as exterior use.

Lastly, the process of brick masonry is completed by cleaning to remove any mortar stains, ultimately resulting in a beautifully finished brick surface, which should be cured later.
