How to calculate number of Bricks per Square meter (m2)

Quantity of bricks depends upon:

1.Size of Bricks

2.Thickness of wall

•Full or 1 brick thick wall

•Half brick thick wall (Partition wall)

3.Thickness of mortar

CASE 1:

Assumptions:-
Size of brick→ 19x9x9 cm (0.19×0.09×0.09 m)
Thickness of mortar = 10 mm
Thickness of wall = Full or 1 brick thick wall

No. of bricks = Volume of brickwork/ volume of 1 brick with mortar

Volume of 1 Brick with mortar = 0.20×0.10×0.10=0.002 m^3

Volume of brickwork = Thickness of wall x Area of brickwork

Volume of brickwork = 0.19mx1m^2 = 0.19 m^3

∴ No. of bricks = 0.19/(0.002) = 95No’s (without wastage)

Consider the wastage percentage as 10 %

Then,

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

If, THICKNESS OF WALL = Half brick thick wall (Partition wall)

Then,

No. of bricks without wastage = 47.5 No’s
No. of bricks with wastage = 52.25 No’s

CASE 2:

Size →23x11x7 cm (0.230×0.110×0.070 m)

Thickness of mortar = 10mm (0.01m)

Thickness of wall = full or 1 brick wall

No. of bricks = Volume of brickwork/ volume of 1 brick with mortar.

Volume of 1 Brick with mortar = 0.240×0.120×0.080= 0.002304 m^3.

Volume of brickwork = 1 m^2 x 0.230 m =0.230 m^3

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

Consider the wastage percentage as 10 %

Then,

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

If, THICKNESS OF WALL = Half brick wall

Then,

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

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