In this article, you will learn the calculation process to find total bricks required for a room.
Calculation process to find bricks required for a room
A) Calculate the size of Room
Generally, the standard size of the room is 12 feet long, 10 feet breadth and 10 feet in height.
And the width of the brick walls is 9 inches.
Length of walls of a room (L) = 12 ft x 2 + 10 ft x 2 = 44 ft
Total Length and breadth of walls of room = 44 ft
Breadth of brick wall (B) = 9″ = 0.75 ft
Height of the room(D) = 10 ft
Volume of brick-work = Length x width x Thickness of wall
= 44*.75*10
= 330 cubic ft =9.345 m³
Deduction of Door = L x B x D = 3 x 7 x 0.65 = ‐13.65 cubic feet
Deduction of Door Lintel = L x B x D = 3.4 x 0.4 x 0.65 = ‐0.884 cubic feet
Total Volume of brick work after deductions = 330 ‐ 13.65 – 0.884 = 315.466 cubic feet
Assuming:-
- Brick size = 9” x 4.5” x 4” = 0.09375 cubic feet
- Thickness of mortar = 0.328 ft (10 mm)
B) Calculate total Bricks required for room
No. of bricks = Volume of brick-work / volume of 1 brick with mortar
= 315.466/0.1089
∴ No. of bricks = 2897 bricks
Volume of 1 Brick with mortar = 9.3937”× 4.8937” × 4.09375” = 188.189 cubic inch = 0.1089 cubic feet
Total Volume of brick:-
Volume of total no.of bricks = brick size in cubic feet x no. of bricks
= 0.09375 cubic feet * 2897 = 271.594
Quantity of mortar = Volume of brick-work with mortar – Volume of bricks
Quantity of mortar = 315.446 – 271.594 = 43.85 cubic feet
Mix Ratio of cement-sand –> 1:6
Dry volume of mortar = Wet volume x 1.53
∴ Dry volume of mortar = 43.85 cubic feet x 1.53
= 67.09 cubic feet
C) Calculate Quantity of cement required for room
Quantity of Cement = Dry Volume of mortar x Cement ratio/Sum of the ratio of mortar
∴Quantity of cement = (67.09 x 1) /(1+6)
= 9.584 cubic feet
Density of Cement = 1440 kg/m³ =40.807kg/cubic feet
∴ Weight of Cement = 40.807 x 9.584
= 391 Kg
1 bag of cement contains 50 kg of cement∴ Number of bags = 391 Kg / 50 k
= 7.82 No’s of bag
D) Calculate Quantity of Sand required for a room
Cement : Sand :: 1:6
Quantity of Sand = Quantity of Cement x 6
∴ Quantity of Sand = 9.584 cubic feet x 6
= 57.504 cubic feet
In this way, you can find total bricks required for a room.
