Aluminium Formwork Essay

Being the second largest urban populated nation in the world, there is an increase in demand for housing in India. Thus leading to popularity of high rise buildings. Aluminium Formwork System saves cost, time and improves the quality of construction. It is successfully used in Japan, Singapore, Malaysia and the Middle East for building apartments, both low and high rises. Aluminium Formwork system is very cost effective for repetition of building layouts and for superstructure. Aluminium Formwork panels can be designed for any component of building such as beams, stairs, columns, balconies, windows and some other special architectural features. The system is unique as all the components in a building, including staircases, window hood, walls,

In comparison to conventional formwork system, aluminium formwork is time saving as the panels are convenient to fix and can be dismantled with ease. Besides number of labors required for the work is less compared to timber formwork. Formwork is a term given to permanent or temporary matrix or all supporting members in a mold, the whole and sole function of which is to give impression and help concrete till sufficient strength to carry its own weight is achieved. It should be able to bear all live loads and imposed loads apart from its own self weight. From past 3 decades there has been great development in the use of formwork systems for concrete construction. The upheaval till now concentrated on environmental issues, health and safety, on-site production which helped the concrete industry towards better quality of construction and improved efficiency. Different range of formwork systems offers wide solutions to concrete construction which facilitates to meet the requirements of a particular

• Doesn 't require timber or plywood for construction activities.
• Slabs and walls can be casted simultaneously.
• Monolithic crack free structures.
• Skilled labors are not required.
• Props are not moved for the removal of floor slab forms.

IV. DISADVANTAGES OF ALUMINIUM FORMWOK SYSTEMS

• Changes made for architectural sound construction not possible on the structure (but openings can be formed or brickwork wall can be constructed for some parts).
• Financial planning must be foremost part of the project due to high speed construction work of aluminium formwork system.
• Form finish is sufficient condition for LIG housing whereas very good quality of paints is required for HIG housing.

V. CASE STUDY
Sayantara, Ahmednagar is based on conventional formwork construction. Total numbers of flats in Sayantara are 20 and total number of floors are 5. Out of 5 floors, 3 are of 1BHK flats and 2 are of 1RK flats. G+4 storey building is constructed. Total area for 1 floor is 1775 sq feet. 4 flats are constructed on each floor. Formwork design is for 1 floor only. After completion of first floor, same is going to repeat for next floor.
