Before Going To Know About Calculation Of Brickwork

Here is our LCETED trivia about brickwork

1 we use 1:5 mix ratio for river sand

2. we use 1:6 mix ratio for M-sand

3. thickness of mortar is should be 10mm

Assume the given data is  

1.   Class A brick (228mm × 107mm × 69m)

2.   Size of the wall for brickwork = 3m x 3m (4") wall

3.   Grade of mortar = 1:6 (cement : sand)

STEP 1: CALCULATION OF BRICKS

No. of bricks = (volume of brickwork/volume of one brick with mortar)

Volume of one brick without mortar = 228x107x69= (mm->m) = (0.228x0.107x0.069) = 0.00168m³

Since Thickness Of Mortar = 10 mm (0.01 m) 228x107x69mm = 238x117x79mm

Volume of brick with mortar = (0.228+0.01) x (0.107+0.1) x (0.069+0.1) = 0.238x0.117x0.079 = 0.002199834m³

Therefore,

No. of bricks of 1m³= 1.0 / (0.002199834) = 454.57

The total volume of the wall for brickwork = 3m x 3m x 0.107m (brick wall thickness 107mm) = 0.963m³

So,

No of bricks needed for the wall = 0.963 x 454.57 = 437.75 - 440 nos of bricks

Consider The Percentage Of Waste As 10 % Or 15 %

Total no. of bricks = 440 + (10 x 440 )/100= 484 - 500 nos

STEP 2: CALCULATION FOR QUANTITY OF MORTAR

Since we need 500 no of bricks for 1m³

Volume Occupied By Bricks = No Of Bricks X Volume Of One Brick

The volume of bricks = 500 x 0.00168 = 0.84m³

Volume Of Mortar = Volume Of Brick Work for 1m³ - Volume Of Bricks

Therefore,

Volume Of  Mortar = 1.0 - 0.84 = 0.16 m³

STEP 3: CALCULATION OF QUANTITY OF CEMENT

Cement = (Dry Volume Of Mortar X Cement Ratio)/ Sum Of The Ratios (Proportion)

Dry volume of Mortar = 0.16 x 1.33 = 0.2128 m³

33% Increment Due To Volume Shrink After Water

LCETED TRIVIA FOR CIVIL ENGINEERS

1 : 6

While working with first-class bricks, it should be noted that for the walls with the thickness of 9” the cement-sand ratio for brick masonry should be 1:6 and when it comes to a wall of 4.5” thickness the ratio can be made 1:4.

 

Cement = (0.2128 x 1) / (1+6) = 0.2128/7 = 0.0304 m³

LCETED TRIVIA FOR CIVIL ENGINEERS

We believe the standard density of 1 cement bag is equal to 1440 kg/m3

Cement  (kg) = 0.0304 x 1440 = 43.776 kg

No. of bags = 43.776 / 50 =  0.87552 bags

Therefore,

1m³ brick masonry needs 500 bricks and 0.87552 bags

So,

0.963m3 of brick wall need of cement bag = 0.963 x 0.87552 = 0.8431 - 1 Bags

STEP 4: CALCULATION FOR QUANTITY OF SAND

Sand = (Dry Volume Of Mortar X Sand Ratio)/ Sum Of The Ratios(Proportion)

OR

Sand = Cement Volume X 6 ( Since 1:6 Grade Of Mortar)

Therefore,

Volume of cement =  0.0304 m³

Sand = 0.0304 x 6 = 0.1824 m³

LCETED TRIVIA FOR CIVIL ENGINEERS

We believe the standard density of 1 m³ sand is equal to 1600 kg/m3

Sand = 0.1824 x 1600 = 291.84 kg /1000 = 0.29184  tonnes 

OR

Sand = 0.29184 x 22 = 6.420 cft  (generally there are 22 cubic feet of sand in a ton)

0.963m³ of brick wall need sand in cft = 0.963 x 6.420 =  6.182 - 7 cft

So, The Result For Given data

1.   Grade of mortar = 1:6 (cement : sand)

2.   Volume of 3m x 3m (4") brick wall = 0.963m³

3.   Class A brick (228mm × 107mm × 69m)

4.   Thickness of mortar = 10 mm

NUMBER OF BRICKS = 500 nos

CEMENT = 1 BAGS OF 50 KG

SAND = 7 cft

How much cement, sand, and bricks are needed for 1 cubic metre of brickwork? 

For one cubic meter (cum) brick wall we need 455 nos bricks, 43.776 kg cement and  6.420 cft sand

 

How much cement, sand, and bricks are needed for 1 square metre of 9" brickwork?

As we now, area of 1 square meter 9” thick brick wall (1 x 1 x 0.225 = 0.225cum) is 0.2225 so we need 102.5 bricks, 9.8496kg cement and 1.4445 cft sand

 

How much cement, sand, and bricks are needed for 1 square metre of 4.5" brickwork?

As we know, the area of 1 square meter 4.5” thick brick wall (1 x 1 x 0.1125 = 0.115cum) is 0.2225 so we need 51.25 bricks, 4.9248kg cement and 0.72225cft sand
