One of the most difficult aspects of building a brick structure is determining how many bricks you will need. Ordering too little can potentially delay your project, while over-ordering is a quick way to throw money down. Bricks are expensive and can quickly add to the cost of your masonry structure.



Quantity of bricks is directly dependent on:

1. Size of bricks

2. Wall thickness

• Full or 1 brick thick wall

• Half  brick thick wall (partition wall)

3. Mortar thickness.

If you want to know how many bricks are needed per square meter or square feet, Let me show you easy ways to work out on brick quantity calculations.


 How to Check the Quality of Bricks at Construction Site?


Calculation 1:

Assume

Actual Brick size = 19 x 9 x 9 cm (0.19 × 0.09 × 0.09 m)

Mortar thickness = 10 mm

Wall thickness = whole or 1 brick thick wall

Volume of 1 brick = 0.20 × 0.10 × 0.10 = 0.002 (with mortar)

Volume of brickwork = wall thickness x area of ​​brickwork

Brickwork volume = 0.19 m x 1  = 0.19  

Thus,

Number of bricks = volume of brickwork/ volume of 1 brick

Number of bricks in sq.m = 0.19 / (0.002) = 95 No.’s (without wastage)

Considering the percentage of wastage as 10%

So we have,

Number of bricks with wastage = 95 + 9.5 = 104.5 No.’s

If wall thickness = half brick thick wall (partition wall)

Then it follows:

Number of bricks with wastage = 52.25 No’s

Number of bricks without wastage = 47.5 No.’s

Calculation 2:

Assume

Brick size  =23 x 11 x 7 cm (0.230 × 0.110 × 0.070 m)

Mortar thickness = 10 mm (0.01 m)

Wall thickness = whole or 1 brick wall

Volume of 1 brick = 0.240 × 0.120 × 0.080 = 0.002304    (with mortar)

Volume of brickwork for 1sq.m = 1  x 0.230 m = 0.230  

Number of bricks = volume of brick with mortar / 1 volume of brick

Number of bricks in 1sq.m = 0.230 / 0.002304 = 99.826 No.’s  = 100 No.s approx. (without wastage)

Considering the percentage of wastage as 10%

So we have,

Number of bricks with wastage = 99.826 + 9.982 = 109.808 = 110 No.’s approx..

If, Wall thickness= half brick wall

Then it follows:

Number of bricks with wastage = 54.904 (55 No.’s)   

Number of bricks without wastage = 49.913 (50 No.’s)
