**What Is Brickwork?**

Brickwork is the laying of brick in a systematic manner with the help of mortar in a number of layers.

In brickwork, bricks are laid horizontally side by side and one above the other to make them strong. The structure formed by placing bricks in such a manner is called a brick masonry wall.

The brickwork calculation and how to calculate the quantity of cement mortar in brickwork and plaster are given below,

**Types of Bricks used in Construction**

The 3 most used bricks used in building construction are as follows,

1. Red Brick

2. Fly Ash Brick

3. Hollow Brick

**Standard Size of Brick**

**1. Red Bricks**

The standard size of Brick in mm is 190 x 90 x 90 mm (Length x Width X Thickness)

Standard Brick Dimensions Inches is 7.48 In X 3.54 In X 3.54 In** **(Length x Width X Thickness)

**2. Fly Ash Brick**

The** **standard size of fly ash brick is 230 mm x 110 mm x 75 mm used in construction.

**3. Hollow Brick**

The standard size of hollow brick is 30x15x15 cm.

**How to Calculate the **Number of Bricks** in A wall (Brickwork Calculation)**

First of all, we do a brickwork calculation for 1 m^{3} of brickwork volume.

The volume of brickwork = 1 m^{3}

Size of brick with mortar = 20 cm x 10 cm x10 cm

The standard size of brick without mortar = is 19 cm x 9 cm x 9 cm

Nos of brick required in 1m^{3} = 1/(0.20×0.10×0.10) = 500 Nos

500 is the number of bricks required in 1 m3 with mortar. It means mortar volume is also calculated in the calculation. So we have to find out the actual number of bricks and the quantity of mortar.

Actual volume of Brick = 500 x (0.19×0.09×0.09) = 0.7695 m3

Volume of Mortar = 1 â€“ 0.7695 = 0.2305 m3

Adding 10% wastage = 0.2305 + (0.2305×10/100) = 0.2305 + 0.02305 = 0.25355 m3

As this is the wet volume of mortar, the dry volume is generally 25% more than the wet volume.

Add 25% Extra volume for a dry volume of mortar.

= 0.25355 + (0.2355×25/100) = 0.25355 + 0.0633875 = 0.3169 m3

So, from the above calculation, we can say that

Nos. of Brick required for 1 m3 of brickwork = 500

Mortar required for 1 m3 of brick = 0.3169 m3

**How to Calculate Quantity of Cement Mortar in Brickwork and Plaster**

1. Quantity of Cement Mortar In** **Brickwork Calculation

Let’s Take an example, The length of the wall = 3 m, width = 2 m, and thickness of the wall = 0.23 m.

Volume of Brickwork = 9 x 5 x 0.23 = 10.35 m3

We know that, for 1m3 brickwork = 500 Nos required

So, for 10.35 m3 of brick work = 500x 10.35 = 5175 Nos.

Also , know that for 1m3 of brickwork = 0.3169 m3 of mortar is required

So, for 10.35 m3 of brickwork = 0.3169×10.35 = 3.28 m3

Now, Let’s find out the quantity of cement and sand in the mortar,

### Mix Ratio 1:4

Consider mortar mix ratio is 1:4

1 part = cement, 4 part = sand

Total part = 1+4 = 5 part

**1. Cement (bags)**

Cement = 1/5 x (volume of mortar)

= 1/5 x 3.28

= 0.656 m3 (volume of 1 bag of cement = 0.035 m3)

= 0.656/0.035

Cement = 18.74 bags = 19 bags

**2. Sand (cu.ft)**

Sand = 4/5 x 3.28

Sand = 2.62 m3

### For Mix Ratio (1:6)

Cement = 1 part, Sand = 6 part

Total Part = 1+6 = 7 part

**1. Cement (Bags)**

Cement = 1/7 x 3.28

Cement = 0.46 m3** **(1 bag volume of cement = 0.035 m3)

Cement = 13.14 bags

**2. Sand (cu. ft.)**

Sand = 6/7 x 3.28

Sand = 2.18 m3

**Summary:**

**1. For Cement Mortar (1:4)**

Cement = 19 bags , Sand = 2.62 m3 (92.52 ft3)

**2. For Cement Mortar (1:6)**

Cement = 13 bags, Sand = 2.18 m3 (77 ft3)

**Cement Mortar Calculation In Plasterwork**

Consider a wall having length = 15 m, width = 8 m with plasterwork thickness =12 mm (0.012m)

First,** **Calculate the Volume of the Cement Plasterwork

Volume of Cement Mortar in Plastering = 15x8x 0.012 = 1.44 m3

Adding 10% wastage = 1.44 + 1.44x(10/100) = 1.44 + 0.144 = 1.584 m3 (wet volume of mortar)

As this is the wet volume of mortar, the dry volume is generally 25% more than the wet volume.

Add** **25% Extra volume for the dry volume of mortar.

= 1.584 + (1.584×25/100) = 1.584 + 0.1584 = 1.74 m3

**Cement Mortar Mix Ratio = 1:4**

1 part cement and 4 part sand (Total Part = (1+4) = 5 part)

**1. Cement (1 part)**

Cement = ( 1 / 4 ) x 1.74

= 0.435 m3 (1 bag volume of cement = 0.035 m3)

= 0.435/0.035 = 12.42

Cement = 12.42 bags

**2. Sand (4 parts)**

Sand = 4/5 x 1.74

Sand = 1.392 m3

**Cement Mortar Mix Ration = 1:6**

Cement part = 1 , Sand Part = 6

Cement = ( 1 / 7 ) x 1.74

= 0.24 m3 (1 bag volume of cement = 0.035 m3)

= 0.24/0.035 = 7.10

Cement = 7.10 bags

**2. Sand (4 parts)**

Sand = 6/7 x 1.74

Sand = 1.49 m3

**Summary**

For 1:4 Mix Cement Mortar: Cement = 12.42 bags, Sand 1.392 m3 (49.15 ft3)

For 1:4 Mix Cement Mortar: Cement = 7.10 bags, Sand 1.49 m3 (52.61 ft3)
