Estimation of building materials is essentially required before starting a new construction project. In our previous article, we have already discussed how to calculate cement, sand, and aggregates. Today we will discuss the easiest method to calculate the required number of bricks in a wall. So let’s start from the beginning.
Volume of the wall.
Volume of a standard brick.
Details of openings in the wall.
1. First, calculate the volume of the wall to be built.
Let us assume,
The length of the wall (l) = 10 foot.
The height of the wall (h) = 10 foot.
Thickness of the wall (b) = 1 foot.
Calculate the volume of the wall by multiplying the length, height, and thickness.
∴ Volume of the wall = l×h×b = 10×10×1 =100 Cu.F
2. Calculate the volume of the brick:
The standard size of a brick (IS Standard) is 190 mm ×90 mm ×90 mm and
with the mortar joint, it becomes 200mm × 100 mm× 100 mm.
l = 200 mm= 0.656168 ft.
b = 100 mm =0.328084 ft.
h = 100 mm = 0.328084 ft.
∴ Volume of the brick = l× b×h = 0.656168× 0.328084× 0.328084 = 0.0706 Cu.F
3. To find out the total nos of brick divide the volume of wall by the volume of the brick.
∴ No. of bricks required = 100/0.0706 = 1416 no. of bricks.
Note: 1. Consider 10% wastages of bricks.
2. If the wall has any openings, subtract the volume of the openings from the volume of wall and then divide it by the volume of brick.
