4.5 inch wall BRICK CALCULATIONS

Assuming:-

Brick size = 9”x4.5”x3”

Thickness of mortar = 0.39

Brick size with mortar= (9+0.39)x(4.5+0.39)x(3+0.39)

                                            =9.39”x4.89”x3.39”

Thickness of wall = 4.5”

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

Volume of 1 Brick = (9/12)x(4.5/12)x(3/12)=0.75’x0.375’x0.25’ = 0.070 CFT

Volume of 1 Brick with mortar = 0.783’x0.408’x0.283’=0.090 CFT.

Volume of Brickwork = 10’ x 6’ x 0.375’ = 22.5 Cubic Foot (CFT) 

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

No. of bricks = 22.5 CFT/ 0.090 CFT

                            = 250 No’s

Brick wastage à 5 to 10 %

Consider 5% brick wastage,

∴ No. of bricks= 250  + (250 x 0.05)

= 250+12.5

=262.5 No’s

So, you will needing 263 number of bricks to construct 10 foot long, 6 foot height & 4.5 inch thick wall.

Likewise you can calculate the number of bricks for any dimension of the wall, procedure for calculation remains same.
