Brick bonds are an important part of the wall structure. "Brick" may be a standard-sized weight-bearing building unit. Bricks are termed as bonds in other ways. Therefore, constructing Brick Masonry is very wanted for building style.
What is Brick Masonry?
Definition of Brick Masonry: When discussing brick masonry, we have to understand ‘brick’ & ‘masonry’ individually. So that we deeply understand how it works in building design & construction.
Brick- A brick could be a building unit within the kind of an oblong block within which length to breadth magnitude relation is two however, height is completely different.
Masonry- Construction of building unit guaranteed alongside mortar
Brick Masonry-The art of laying bricks in mortar in a very correct systematic manner that provides consistent mass that might stand up to forces while not disintegration, known as Brick mason
The Features of Brick Masonry
Brick Masonry has some features. Such as:
- Its hearth resistance, size, durability, workability & economical profit.
- A brick will not burn, buckle, or soften.
- The Brick will not rot and permit Termites to invade.
- A brick will not dent, devalue, rust, and corrode.
- A brick will notate from the Sun’s ultraviolet Rays.
- A brick will not be broken by high winds, rain, or hail.
- A brick will not need constant maintenance.
- The brick will not limit personal expression & choices.
Manufacturing of Bricks
To manufacture a brick masonry wall, engineers would like raw materials like fly ash, gypsum, cement & sand that area unit manually fed into a pan mixer wherever water is supplementary within the needed proportion for intimate commixture. The proportion of the raw material is mostly within the ratio of 60-80% of fly ash, 100% mineral & 8-10% cement, relying upon the standard of raw materials. After the commixture, the mixture is shifted to the hydraulic or mechanical presses. The bricks are carried in pellets.
Types of Brick Masonry
There are two types of brick masonry work. Such as:
- Brickwork in mud: The mud is employed to extra service the joints. The thickness of the mortar joint is 12 mm which is the most cost-effective. The height of the wall is 4 mm.
- Brickwork in cement: In this process, the work is divided into three (3) classes. Such as:
- I CLASS- During this kind, cement or lime mortar is employed. The surfaces and edges of bricks are sharp. The thickness of the mortar joints does not exceed 10 mm.
- II CLASS- In this kind, ground-shaped bricks are used. Bricks are rough and the form is slightly irregular. The thickness of the mortar joint is 12 mm.
- III CLASS- In this kind, bricks do not seem to be exhausting however rough surface with distortion. This sort is employed for temporary structures and used in places where rainfall is not significant.
Types of Brick Shape
In the brick masonry work, bricks’ shapes are counted for making a well-constructed masonry wall. Some shapes that are counted such as:
- Solid bricks: Solid bricks do not have holes, cavities, or depressions.
- Perforated bricks: Perforated bricks have holes not prodigious the twenty-fifth of the gross volume of the brick; minimum 30% solid across the breadth of brick.
- Frogged bricks: Frogged bricks have depressions in one or a lot of bed faces however, their total volume shall not exceed 200th of gross volume of a brick.
In brick masonry, some joints strengthened the wall. Such as:
- Weathered joint -Mortar joint features a slanting (downwards) edge.
- Concave joint -Joint acetabular inwards.
- Vee joint -Mortar joint within the sort of V.
- Flush joint -Mortar joint is flush with the brick façade.
- Raked joint -A giant portion of the mortar joint is raked out not a secure, impermeable joint.
- Stripped joint - A medium-large portion of the mortar joint could be a safe leaky joint.
- Struck joint -Mortar joint features a slope (upwards) edge
Tools that are used in Brick Masonry Work
To construct and make brick masonry, workers need some tools that help them to get the right proportion and mix of a brick masonry wall or just the work. The tools are-
- Plumb bob
- Spirit level
- Mason square
- Steel tape
Brick Course & Closures
In brick masonry work, some courses & closures measure the right & different shapes of bricks. Such as:
- Queen Closure: A brick cut in half down its breadth.
- King Closure: A brick cut a corner & joining middle points of thickness and breadth of the brick.
- Three-Quarter Bath: A brick cut to three-quarters of its length, and lay with its long, narrow side exposed.
- Half Bat: A brick cut in half over its width and laid in the wall construction
- Quarter Bat: A brick cut to a one-fourth of its length.
