ALUMINIUM FORMWORK TECHNOLOGY

- Nov 27, 2017 -

Aluminium Formwork System, saves cost, time and improves the quality of construction. For repetition of building layouts and for above-the- plinth work, Aluminium Formwork system is very cost effective. This system is unique as all the components in a building, including slabs, floors, walls, columns, beams, staircases, balconies and window hood, are concrete and there is no need for block works or brick works. As all the periphery of resulting structure/component is concrete and at the same time we can control the concrete quality, the durability of the structure increases. It gives form finish, eliminates the need for external and internal plaster and the walls can be directly painted with a minimal skim coat, all these ultimately resulting in cost saving.

For 100 per cent work, construction through slab beam wall construction takes X time and through Aluminium Formwork technology the time required is 1/6th of the X time. The technology is environment friendly as there is no use of timber. The formwork gives the box or cellular design resulting in the walls giving support to the super structure in two directions. As a result, the structures are more resistant to earthquakes than the traditional RCC column and beam designs. As the Aluminium Formwork is lightweight, no tower cranes are required for the same unlike in tunnel framework. Due to simplicity of the assembly, only unskilled labours are required with minimal supervision. The Aluminium Formwork System is removable and can be used up to one hundred times with little maintenance. Moreover, the requirement of steel is also reduced in this technology as aluminium has a higher scrap value.


FEATURES OF ALUMINIUM FORMWORK TECHNIQUE

Features of aluminium formwork technique are as follows: -

1.Versatility

2.Speed

3.Quality

4.Durability

5.Cost.


ADVANTAGES OF ALUMINIUM FORMWORK SYSTEMS

   - For LIG housing brickwork, internal and external plaster is not required, saving Rs.

   - 125/- per sq.ft. For HIG housing a 5 mm coat of external sand faced plaster may be necessary.

   - Savings on overhead expenses due to speedy construction (4-5 days per floor).

   - Monolithic crack free structures.

   - Doesn't require timber or plywood for construction activities.

   - Casting of walls and slabs possible simultaneously.

   - Floor slab forms removed without moving props.

   - Earthquake resistance of resulting structures increases manifold.


DISADVANTAGES OF ALUMINIUM FORMWOK SYSTEMS

  - Architectural changes not possible on the structure (but some walls can be of brick work or openings can be entertained).

  - Due to the tremendous speed of construction, working capital finance needs to be planned in advance.

  - Paints for HIG schemes needs to be of superior quality. For LIG, form finish is more than sufficient.


MOST APPROPRIATE USE

1.Mass housing with repetitive design.

2.Redevelopment projects.

3.Specialized contractor.
