How do you find the shuttering of a plinth beam?
- Take the cross-section of beam and measure the lengths of the two sides and base of beam.
- Sum the three measurements.
- Measure the span of the beam.
- Multiply the span length by sum of the three measurements (beam base two vertical sides) gives the shuttering area of beam.
When should shuttering be removed from beam?
Complete slab shuttering should be removed after 10 days. Beams removal of sheeting required 8 days. Beams and arches complete removal of shuttering required 14 days. If beams and arches are of span more than 6 meter, then shuttering removal time should be 21 days.

Which cement is best for plinth beam?
Portland Pozzolana Cement (PPC) is the ideal cement to be used as it hydrates slowly and gives high final strength.
How do you calculate footing shuttering?
2. Rectangular Footing:
- Volume of concrete = Area of sq. footing x Depth of sq footing. Area of sq. footing = L x B = 1 x 0.7 = 0.7 m² Volume of concrete = 0.7 x 0.25 = 0.175 m³.
- Shuttering area = 2 (L + B) x D. = 2 (1+0.7) x 0.25. = 0.85m²
- Bitumen paint area = Shuttering area + (Top area of footing – column area)
Is formwork and shuttering the same?
Formwork is a temporary structure which is used as a mould to pour the concrete. Formwork may be the horizontal or vertical arrangement, made to keep concrete in position until it gains desired strength and shape. Shuttering is a part of formwork. Formwork for columns, retaining walls, footings are known as shuttering.

Which shuttering is best?
Steel shuttering plate is the best type of shuttering because this is watertight shuttering which can bear the load of cement concrete placed on it. This shuttering can be used for horizontal, vertical or any other shape required for the work. It gives a leveled surface which has a good appearance.
