These considerations demonstrate that the type of brick used plays a crucial role in determining how many bricks are needed to fill a square meter. Thus, accurate measurements and proper techniques are essential for effective calculations.
What Calculation Method Should Be Used to Determine Bricks per Square Metre?
To determine the number of bricks per square metre, you should use the area of the wall and the size of the bricks to perform the calculation.
Here are the main points related to this calculation method:
1. Size of the brick
2. Mortar joint thickness
3. Area of the wall
4. Brick laying pattern
To further expand on these points, we will define each one and explain its relevance to the calculation.
-
Size of the Brick: The size of the brick significantly affects the number of bricks needed per square metre. Standard brick sizes vary by region but commonly measure approximately 215 mm x 102.5 mm x 77 mm in many countries, including South Africa. Calculating the area of one brick by multiplying its length and height helps in determining how many bricks fit into one square metre (1 m²).
-
Mortar Joint Thickness: The mortar joint thickness also impacts the total number of bricks. Mortar joints typically range from 10 mm to 15 mm in thickness. The space added by the mortar must be included in the calculation. For instance, if a brick is laid with a 10 mm mortar joint, the effective size of the brick becomes larger. Accurate measurement ensures you account for this additional volume in your total count.
-
Area of the Wall: The total area of the wall is crucial for determining how many bricks will be required. For example, a wall that measures 2 metres high and 5 metres wide has an area of 10 m². The number of bricks per square metre can be multiplied by the wall’s area for a comprehensive total. Accurate wall dimensions are essential to avoid overestimation or underestimation of brick requirements.
-

How Does Mortar Thickness Impact the Calculation of Bricks?
Mortar thickness impacts the calculation of bricks by affecting the total measurement of each unit and, consequently, the overall quantity required for a given area. When calculating the number of bricks needed for construction, the standard size of a brick is often used. This measurement typically does not include the mortar gap. If the mortar thickness increases, the total dimensions of each brick-plus-mortar unit also increase.
Step one involves determining the dimensions of the brick itself. For instance, a standard brick measures approximately 190 mm long, 90 mm wide, and 57 mm high. Step two requires measuring the mortar joint. Commonly, mortar thickness ranges from 10 mm to 20 mm. Step three combines the brick size with mortar thickness to find the new effective dimensions. For example, if you add a 10 mm mortar joint to the brick, the total length becomes 200 mm (190 mm brick plus 10 mm mortar).
Next, calculate the area based on these new dimensions. If the effective size of the brick with mortar is now 200 mm long and 100 mm wide (90 mm brick plus 10 mm mortar), the area of one unit becomes 20,000 mm². Step five divides the total area you need to cover by the area of one unit. If the area to be covered is 1 m² (1,000,000 mm²), then 1,000,000 mm² divided by 20,000 mm² equals 50 bricks.
In conclusion, as mortar thickness increases, the overall size of each brick unit increases. This change leads to a lower total count of bricks required to cover a specific area. Thus, when performing calculations, it is crucial to include the mortar thickness to ensure accuracy in estimating the number of bricks needed.
