In this article,
we explained How much cement, sand, and bricks are required for 1 square
foot and 1 cubic foot of 9” and 4.5” brickwork wall
Let’s dive
The thickness of
the brick wall = 9” - 0.75’
Volume of 9” brick
work (1 sqft) = 1 x 1 x 0.75 = 0.75cft
We will take brick size - 9″× 4.5″×3″
Size of one brick =
9″× 4.5″×3″ - 0.75’ x 0.383’ x 0.25’
Consider, Thickness
of mortar = 0.4 inch = 12 mm
Step – 1: Calculation of bricks needed for 1sqft and cft
Volume of 9” brick without mortar =
0.75’ x 0.383’ x 0.25’ = 0.0718125 cft
The volume of 9” brick
with mortar
By adding the
thickness of the mortar
Length of Bricks
in meter (L) = 9” + 0.4” = 9.4” - 0.783’
Width of Bricks in
meter (W) = 4.5” + 0.4” = 4.9” - 0.4083’
Thickness of
Bricks in meter (T) = 3” + 0.4” = 3.4” - 0.283’
Size of the brick with mortar in feet
= 0.783’ x 0.4083’ x 0.283’
Volume of 9” brick with mortar =
L x W x H = 0.783’ x 0.4083’ x 0.283’ = 0.09047 cft
No. of bricks for 1sqft = (volume of 1sqft brickwork/volume of one brick with mortar)
No. of bricks for
1sqft = (0.75/0.09047) = 8.290nos
No. of bricks for 1sqft = 8.290 nos
Step 2: Calculation for the quantity of mortar for
1sqft
Since,
We need 8.29 no of
bricks
The volume occupied by bricks = No of bricks x
volume of one brick
Volume of bricks = 8.290 x 0.0718125 = 0.5953 cft
The volume of Mortar = Volume of Brick Work -
Volume of Bricks
Therefore,
Volume of Mortar = 0.75
- 0.5953 = 0.1547cft
Dry volume of Mortar = 1.33 x 0.1547= 0.205751m3
(33% increment due to volume shrink after water)
Step 3: Calculation for quantity of cement for
1sqft
Cement = (Dry volume of mortar x Cement
ratio)/ sum of the ratios (proportion)
Cement= (0.205751 x 1) / (1+6) = 0.205751/7 = 0.029393 cft
Density of cement = 1440Kg/m3
Which means for 1m3 = 1440Kgs required.
Therefore 1cft = 1440/35.315 = 40.775/cft
Since, Density of cement = 40.775/cft
Cement (kg) = 0.029393
x 40.775 = 1.1984 kg

Step 3: Calculation of quantity of Sand for 1sqft
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,
Sand = 0.029393 x
6 = 0.1763
Density of sand = 1600Kg/m3
Which means for 1m3 = 1600Kgs required.
Therefore 1cft = 1600/35.315 = 45.30/cft
Sand = 0.1763 x
45.30 = 7.98 kg / 1000 = 0.00798 tonnes
Sand = 0.00798 x
22 = 0.17556 cft
So, For 1 sqft brickwork we need
Bricks = 8.29 nos
Consider the Percentage of Waste As 10 % Or 15 %
Total no. of bricks = 8.29 + (10 x 8.29)/100 = 9.119 - 10 nos
Bricks needed for 1sqft brickwork = 10 nos
Cement needed for 1sqft brickwork = 1.1984 kg
Sand needed for 1sqft
brickwork = 0.17556 cft
How much cement, sand, and bricks are needed for 1 square foot of 9” brickwork?
For one square foot (sqft) 9” brick wall we need 10 nos bricks, 1.1984
kg cement and 0.17556 cft sand
How much cement, sand, and bricks are needed for 1 square foot of 4.5” brickwork?
For one square foot (sqft) 4.5” brick wall we need 5 nos bricks, 0.5992kg
cement and 0.087cft sand
How to calculate bricks, cement and sand for one cubic foot (cft) of brickwork?
As we know, the area of 1 cubic foot 9” thick brick wall (1 x 1 x 1 = cft)
is 1cft so we need 14 bricks, 1.597kg cement and 0.2340 cft sand
How many bags of cement are required for 100 sqft brickwork?
As we know 1sqft brickwork
need 1.1984 kg cement therefore 100 sq/ft brickwork need 100 x 1.1984kg = 119.84
kg so, No.
of bags = 119.84 / 50 = 2.3968 bags approximately 3 bags need for 100 sq/ft
brickwork
How many bags of bricks are required for 100 sqft brickwork?
As we know 1sqft of brickwork
needs 10 nos bricks. therefore 100 sq/ft brickwork need 100 x 10 = 1000 nos. so,
1000
bricks need for 100 sq/ft brickwork
How many bags of sand are required for 100 sqft brickwork?
As we know 1sqft brickwork need
0.065 cft sand therefore, 100 sq/ft brickwork need 100 x 0.065 = 6.5cft. so,
6.5
cft sand need for 100 sq/ft brickwork
