Brick is a construction material it’s made up with clay, composition of brick is Lime 2 to 5% Alumina-clay 20 to 30%, Silica-Sand – 50 to 60%, Bricks are rectangular blocks of backed clay which is used to construct a walls and payment and other some masonry in construction.
Brick Masonry is constructed by placing of brick with mortar which is called as brick masonry Brick masonry is a highly durable form of construction
How to calculate brick quantities in brick masonry Wall
For Example Wall Size is
Length (L) -1m, Height (H) – 1m and Width(W) is-1m
Standard brick Size – 190 x 90 x 90 mm / 0.19 x 0.09 x 0.09 m (Without Mortar)
Mortar Thickness is -10mm
Brick Size with Mortar – 200 x 100 x 100 mm / 0.20 x 0.10 x 0.10 m
Formula to Find the Number of Brick Quantity in Wall is
Formula = Volume of Wall / Volume of One Brick
Volume of Wall = Length (L) x Width (W) x Height (H)
Volume of Wall = 1 x 1 x 1 = 1.0 mᶟ
Volume of one Brick without Mortar = 0.19 x 0.09 x 0.09 = 0.00154 mᶟ
Volume of one Brick with Mortar = 0.20 x 0.10 x 0.10 = 0.00200 mᶟ
So, No of brick required in 1mᶟ of Wall is
No of Brick without Mortar = 1.0 / 0.00154 = 650 Nos
No of Brick with Mortar = 1.0 / 0.0020 = 500 Nos
Usually Wastages considers 5% in brick Work
No of Brick with Mortar = (1.0 / 0.0020)+5% of Total Nos of Bricks
No of Brick with Mortar = (500)+(500*5%) = 525 Nos of Bricks Requires
1. Brick Without Mortar (190 x 90 x 90) mm Size Required in 1mᶟ = 650 Nos
2. Brick With Mortar (200 x 100 x 100 ) mm Size Required in 1mᶟ = 500 Nos (Without wastage)
3. Brick With Mortar (200 x 100 x 100 ) mm Size Required in 1mᶟ = 525 Nos (With wastage 5%)
