# Classification of Bricks:-

**Bricks are usually classified into two types:-**

Fired brick and Non fired brick. and they are further Classified into three classes based on the quality of brick. “First Class, Second Class and third class bricks.”

## Composition of brick:-

**Alumina:-** A good class brick consists of 20-30% of Alumina. Excess of Alumina in clay makes the brick crack and wrap on drying.

**Silica:-** In general, bricks are made with 50-60% of Silica in it. Excess of Silica in brick makes the brick to brittle.

**Lime:-** Brick consists of 0.8-2% of Lime in it. Excess of lime in brick may cause to melt and distort during burning.

**Other constituents:- **Magnesia, Sodium, potassium, manganese and iron oxide.

**Frequently Asked Questions:- **

**1. No. Of Bricks required for 1 Cubic Metre or 1m**^{3}. (Brickwork Calculation)

^{3}. (Brickwork Calculation)

To calculate this follow the below Steps-

**Step-1:- **Calculate the Volume of Single brick:

Standard Size of Brick is varied according to the region. In India, the standard size of brick is **190mm x 90mmx 90mm. ** Well, this method is same for any size of brick. But for calculation, I am considering mostly used size of brick in globe.

**the size of brick is 9″x 4″x 3″**

**Step-2:- **Unit Conversion

Converting inch to m for ease in calculation. If you are unable to convert units use Google Conversion tools.

Total Volume = 9″x4″x3″ = 0.2286m x 0.1016m x 0.0762m

**Volume of Brick in Cu.m = 0.00176980 cu.m**

**Step 3:-**

Volume required = 1m x 1m x 1m

**Total Volume Required = 1Cu.m or 1m ^{3}**

**Volume of Each brick = 0.0017698m ^{3}**

No. of Bricks in 1m3 = 1/0.0017698 = 565 Bricks

**Hence, 565 bricks are required for 1 cubic metre or 1m ^{3} of bricks.**

## 2. How to Calculate No. of Bricks required in a wall of

10′ x 10′. (Brickwork calculation)

Bricks are bonded each other using 1:6 Cement Masonry. We generally adopt 10-16mm of thickness between each layer of Bricks.

Therefore, the standard thickness of Cement Masonry layer in Brickwork is **0.39″ or 10mm**

**Step 1:-** Adding mortar thickness to brick

Size of brick is 9″x 4″x 3″

Add 0.39″ to all sides of brick (9″+0.39″, 4″+0.39″,3″+0.39″)

The size of brick with mortar thickness is **9.39″ x 4.39″ x 3.39″**

**Step 2:- **Unit Conversion

For ease in calculation convert (9.39″x 4.39″ x 3.39″) inch to ft

= 0.78ft x 0.36ft x 0.28ft

Consider Front face area of the brickwork in calculating the no. of bricks

From Fig4: Front face area of brickwork = L x D

Area of Total wall (L x D) = 10′ x 10′ = 100Sft [Front face area]

Area of Each Brick (L x D) =0.78′ x 0.28′ = 0.218Sft (With Mortar thickness)

**Step 3:- ** Deductions in brick masonry for Brickwork calculation.

RCC Bed is provided for every 3ft of height of Brickwork.

As per above figure Length and Height of brickwork is 10Ft x 10Ft Height,

For 10′ height there must be 2 Beds in brickwork.

#### Dimensions of RCC Bed in Brickwork calculation:-

The length of bed go up to the length of brick work and bed is attached to Columns for transferring the vertical load.

Depth or thickness of the bed may varies between 3″ to 4″. (Refer above fig)

(Let us consider the maximum i.e., 4″ or 0.33′)

**The length and Depth of Bed is 10′ x 0.33′ [Front Face area]**

Front face area of bed (L x D) = 10’x0.33′ = 3.3SFT

There are Two beds in brickwork so = 2×3.3SFT = 6.6 SFT

**Deduct the area of RCC Bed from the above wall area for Brickwork calculation**

Therefore, 100Sft – 6.6Sft = 93.4Sft

Front face Area of Each brick = 0.218Sft

Total No. of Bricks = 93.4/0.218 = 428 Bricks required (approx)

**Result :-** For 10′ x 10′ wall of Brickwork approximately **428 bricks** required.

## Quantity of cement, Sand or Mortar Required for Brickwork:

1:6 ratio of cement mortar is usually used for brickwork. In order to calculate the amount of Cement, Sand or Mortar required or brickwork firstly find out the amount of mortar required for brickwork.

Volume of Each brick = 9″ x 4″ x 3″ = 0.22 x 0.1 x 0.07 = 0.00154m^{3}

As we know that, 0.39″ mortar thickness is added to brick size. Hence

Volume of each brick with mortar = 9.39″x4.39″x 3.39″ = 0.238 x 0.111 x 0.081 = 0.00228m^{3}

Therefore, amount of mortar required for each brick = 0.00228-0.00154 = **0.00074m ^{3}**

From above, No. of bricks required = 428 bricks

Volume of mortar required for 428bricks = 428 x 0.00074 = 0.316m^{3}

After adding water to the mortar mix, it bulks and reduces the volume by 33% during wet condition. In order to calculate the dry volume of cement & sand or Brick mortar add 33% of extra volume to it.

Dry volume of mortar = Wet volume of mortar x (1+0.33) [33% of volume]

Dry volume of mortar = 1.33 x Wet volume of Mortar = 1.33 x 0.316= 0.420m^{3}

1:6 ratio of mortar for brickwork which means cement:sand = 1 part of cement and 6 parts of sand.

Total parts = 7

**Amount of cement required for mortar:**

The qty of Cement required for Brick mortar = Dry volume of mortar x 1/7 = 0.420 x 1/7 = 0.06m^{3}

Density of cement = 1440Kg/m^{3}

Which means for 1m3 = 1440Kgs required.

For 0.106m3 = 0.06×1440=**86.4Kgs **

**Amount of Sand required for mortar:**

Similarly as Cement, Sand is calculated in terms of m^{3}

The Amount of Sand required for Brick masonry = Dry volume of mortar x 6/7 = 0.420 x 6/7 = 0.36m^{3}

In terms of Kgs, Density of Sand = 1600Kgs/m^{3}

For 0.36 = 0.36x 1600 =** 576Kgs**

Summary:For Brickwork of 10′ x 10′ where each Size of brick = 9″x 4″x3″

- No. of Bricks without mortar = 533 bricks
- The no. of bricks with mortar = 458 bricks
- No. of bricks with RCC bed & mortar = 428 bricks
- The quantity of mortar required = 0.42m
^{3}- Amount of cement required = 87kgs
- The amount of sand = 0.36m
^{3}

thanks sir it is really helpfull for everyone

Hello sir good evening,

Thanks for your correction

Appreciated.

Thanks for this basic knowledge about bricks .

Thank’s a lot

Thanks .but I need more technical tips.

Comment Text* all technology topics are not download sir . I want to downloaded all topic and book download. and I must be need the book and note is Foundation engineering, irrigation engineering , sanitary engineering and steel structure design and timbers design quick sir

Its really great effort. Thank very much

It’s really really great for starters

Really a great effort sir….very informative

Thanks for Your inputs. 🙂

Sir, for wall calculation of bricks. In 9″wall we have two rows alternate header and stretcher in row .your calculations for one row or two rows.

i considered normal its just one row

Really informative sir.. thanks a lot.

That you very much Sir…you have really left a great impact in us upcoming Engineer. I really appreciate your effort towards achieving this and look forward for more knowledge . thanks Sir once again

thanks for ur comment

THANKS FOR YOUR ALL INFORMATION.

thanks for your comments

Excellent sir

sir what is that 1.33% means? we have to find the bulkage of sand so we do 33/100 so 0.33 only we should get why adding 1 in that 0.33?

0.33 is extra volume which we need to add

sir pls help me in this regard ,its a small doubt but big thing to clarify it.

yes buddy tell me

Sir we highly appreciate your efforts make us understand those formula. Thnx

Sir, quantity of sand is calculated in cu m . But in market they sell in ft . I am confused state how I ordered the sand

use google tool to convert

It’s been a great article and i actually wanted to know about these different types of bricks an its classification and i personally feel this article going to clear all of your doubts regarding to this topic so i am going to bookmark this for further reference.Thank You.

Sir, very good use full for young generation. I really appreciate and convey my thanks to you.

The above example is for partition wall or for 9″ wall? How to calculate mortar quantity for partition wall?

Refer the article once again the procedure is same for any width of wall

Thank you and I appreciate your efforts sir.

Really very use full sir .

Thank you so much sir.

I am Glad !

428 bricks is for partition wall.

For 9″ wall thickness we have to double the no.

So it is 856 bricks

sir 9″ wall cement use per sqft

special thanks to you for your kind explanation

When you get the volume of mortar ,how do u get each part
