Calculation of Bricks Required for a 2.0m x 45m Wall
Calculation of Bricks Required for a 2.0m x 45m Wall
To accurately determine the number of bricks required for a 2.0m x 45m wall, several factors need to be considered. These include the type of wall (single leaf or double leaf), wall thickness, bonding method, and any additional requirements such as coping and piers.
Dimensions and Wall Thickness
The dimensions of the wall are 2.0 meters in height and 45 meters in length. Depending on the thickness of the wall, the number of bricks required will differ. For a single leaf wall, which is typically 105mm thick, and a double leaf wall, which is 215mm thick (9 inches).
Brick Calculation for a Single Leaf Wall (105mm)
A single leaf 105mm wall requires 60 bricks per square meter (sq.m). The calculation for a 2.0m high x 45m long wall is as follows:
Total area of the wall 2.0m x 45m 90 sq.m
Bricks required 90 sq.m x 60 bricks/sq.m 5400 bricks
Brick Calculation for a Double Leaf Wall (215mm)
A 215mm wall (9 inches thick) requires 120 bricks per square meter. The calculation for a 2.0m high x 45m long wall is as follows:
Total area of the wall 2.0m x 45m 90 sq.m
Bricks required 90 sq.m x 120 bricks/sq.m 10800 bricks
Additional Considerations
Additional considerations include the use of piers and coping.
Piers
Piers are necessary to support the wall and prevent it from sinking. The number and placement of piers depend on the wall's width and the material used. For a 2.0m high x 215mm thick wall, you will need approximately one pier every 2 meters. Each pier is 440mm wide and protrudes 105mm.
Total piers 45m / 2m 22 piers (one for each end and 2m apart)
Bricks required for piers 22 piers x 600 bricks/pier 13,200 bricks (approximately)
It is advisable to round up to ensure sufficient materials are available.
Coping
The top of the wall, referred to as the coping, needs to be constructed carefully. For a single leaf 105mm wall, the coping will be laid on edge. For a 215mm wall, English bond may be more suitable.
Final Brick Calculation
Assuming a 215mm thick wall with English bond, the final calculation is as follows:
Total bricks required 12000 bricks for the wall 13200 bricks for piers 25200 bricks
This equates to approximately 20 pallets of 500 bricks each.
Conclusion
Accurately calculating the number of bricks required for a wall involves several steps and considerations. By taking into account the type of wall, thickness, bonding method, and additional features such as piers and coping, you can ensure that you have the correct amount of bricks.
Note: It is always wise to add extra bricks to account for breakage and waste during the construction process. A common rule of thumb is to add 10% to 15% to your final calculation.
