How to Calculate the Required Number of Bricks in Brick Masonry Work

Total Area of a Unit = x.y

x = 450mm = 0.45m

y = 150mm = 0.15m

xy = 0.0675 m2

Total Area of Brick Per Unit

(x-20)(y-20) = 0.43 x 0.13 = 0.0559 m2

Let's find the Nr of units per 1m2

Nr of Units = (1/0.0675) = 14.8

Hence, Nr of Bricks Per 1m2

= 14.8 x 4

= 59.2 Nr

We can Calculate Required amount of mortar per 1m2 by below equation.

Requires Amount of Mortar = 14.8 x 0.1025 x (0.0675-0.0559)

                                              = 1.517 x 0.012

                         

                                              = 0.02 m3
