Shuttering is temporary structure used in construction for poured fresh concrete for different structural members. After casting when concrete is achieve strength then shuttering removed. Shuttering is also known as a formwork. Shuttering is always calculated in square meter unit.
In this article we have discussed about the calculate shuttering quantity for beam & slab.
Calculate shuttering quantity for Beam & slab
Shuttering Quantity for Beam:
To calculate shuttering quantity first of all you need to perimeter of any shape.
Here is the formula to calculate perimeter.
Perimeter of Square shape – 4 x Sides
Perimeter of Rectangle shape – (2 x L) + (2 x B)
Perimeter of circle – 2¶R (where R is radius of circle)
Formula to calculate shuttering area:
Shuttering area = Perimeter length x depth
Calculate Shuttering quantity of Beam:
- Beam Length = 4 m
- Beam depth = 300 mm
- Beam Width = 200 mm
Beam shuttering is done on 3 sides of beam. The beam top surface is not done because concrete is fill using top surface.
Shuttering Area Beam of face 1
= L x B = 4 x 300/1000
= 1.2 sqmt (Here depth is convert into meter 1 m = 1000 mm)
Shuttering Area Beam of face 2
= L x B = 4 x 300/1000
= 1.2 sqmt (Here depth is convert into meter 1 m = 1000 mm)
Shuttering Area Beam of face 3
= L x B = 4 x 200/1000
= 0.8 sqmt (Here depth is convert into meter 1 m = 1000 mm)
Total Shuttering area of beam = 1.2 + 1.2 + 0.8 = 3.2 sqmt
Calculate shuttering area of slab
Slab are rest on beam, so there is no need to provide four sides shuttering. In the beam & column top portion is open to fill concrete same followed for slab. So slab shuttering only bottom shuttering can be done.
Shuttering quantity for slab:
- Length of slab – 5 m
- Width of slab – 3 m
Shuttering area of slab
= L x B
= 5 X 3
= 15 sqmt
So these are the methods to calculate shuttering quantity for beam & slab. I hope this helpful to calculate shuttering quantity. If you have any query then you comment in the comment box.
