**What Is Brick work?**

**Brick work** is the **laying of brick** in a **systematic manner** with the help of** mortar** in a n**umber 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 brick work calculation and how to calculated quantity of cement mortar in brickwork and plaster is 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 Number of Brick in A wall (Brick work Calculation)**

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

**The volume of brick work = 1 m ^{3}**

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

Standard size of brick **without mortar** = **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 i**s 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** numbers 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 – 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 wet volume.**

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

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

So, from above calculation we can say that

**Nos. of Brick required for 1 m3 of brick work = 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 **Brick work Calculation

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

Volum**e 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 find out quantity of cement and sand in mortar,

### Mix Ratio 1:4

**Consider mortar mix ration 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 Volume of Cement Plaster work**

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

Add** 25% Extra** volume for **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 part)**

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 part)**

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)**
