Most of the structural buildings comprise 75% of brickwork (at least in Asian countries).

So it is essential to learn the **brickwork calculation**,

Before beginning the calculation, be familiar with the types of brick bonds that we covered in the previous post.

In this post, we are going to explain,

- Brickwork Calculation & Formula

- How to calculate bricks per square foot

- How to calculate cement quantity & Sand in brickwork

## Brickwork Basics

Let’s learn the basics,

- Ensure to read the brickwork construction procedure provided by the client

- Cement mortar ratio should be 1:6 for 9” Brickwork and 1:4 41/2” brickwork

- Mortar thickness should not be more than 10 mm between the courses and sides of the bricks

- Ensure you are using good quality of cement and sand. (Silt Content Test)

- Ensure you have all the Civil tools required for the construction.

# Brickwork Calculation & Formula

- The size of the modular brick is 190 X 90 X 90 (refer the picture)
- Mortar Thickness is 10mm
- Assume required brickwork volume is 1 cubic metre (m
^{3})

Any brick walls consist of bricks and cement mortar.

So, first of all, we are going to find the volume of bricks with mortar thickness and then volume of bricks alone.

### Volume of bricks with mortar

Volume of 1 brick with mortar = 200 X 100 X 100 ( 10 mm mortar thickness on all sides)

= 0.2 X 0.1 X 0.1

**Volume of brick with mortar = 0.002 Cum (m ^{3})**

Therefore, Number of bricks required for 1 cubic metre = 1/0.002 = 500 No.s

### Volume of bricks without mortar

Volume of 1 brick without mortar = 190 X 90 X 90

= 0.19 X 0.09 X 0.09

Volume of 1 brick without mortar = 0.001539 Cum (m^{3})

Volume of 500 bricks without mortar = 500 X 0.001539 Cum

**Volume of bricks without mortar for 1 cum = 0.7695 Cum (m ^{3})**

Therefore,

Required amount of cement mortar = 1 Cum – Volume of bricks without mortar

= 1 – 0.7695

**Required amount of cement mortar = 0.2305 Cum (m ^{3})** (Wet Condition)

Dry volume of a mortar = 0.2305 cum X 1.33 = 0.306565 cum

We know the mortar ratio is 1:6 (1 part Cement & 6 Part Sand = 7 Part)

Required amount Cement quantity in brickwork = 0.306565 X 1/7 X 1440 kg

Required amount Cement quantity = 63 Kg = 1.26 bags (50 Kg bag)

Required amount of Sand = 0.306565 X 6/7 = 0.26277 Cubic metre (m^{3})

Therefore, For 1 cum of brickwork, we need

- 500 Numbers of bricks
- 63 kg of cement
- 0.263 m
^{3 }of sand.
