Aluminium Formwork system
The Aluminium Formwork System was developed by Company from Malaysia in late 1990s as a system for constructing mass housing project in developing countries. The units were to be of cast-in-place concrete, with load bearing walls using a formwork of aluminium panels. To be erected by the hundreds, of a repetitive design, the system ensured a fast and economical method of construction. The concrete surface finish produced with the aluminium forms allows achievement of a high quality wall finish without the need for extensive plastering.
This is one of the systems identified to be very much suitable for Indian conditions for mass construction, where quality and speed can be achieved at high level. The speed of construction by this system will surpass speed of most of the other construction
Genenral specification of Aluminum Formwork System
The basic element of the Aluminium Formwork System is the panel, which is an extruded aluminium Component section, welded to form a Panel.
This produces a lightweight panel with an excellent stiffness to weight ratio, yielding minimal deflection under concrete loading
Panels are manufactured in the size and shape to suit the requirements of specific projects. The panels are made from high strength aluminium alloy with a 4 mm thick skin plate and 6mm thick ribbing behind to stiffen the panels
Once they are assembled they are subjected to a trial erection in order to eliminate any dimensional or on site problems.
The formwork components are durable they can be used repetitively up to 200 times. It is light weighted so heavy lifting is eliminated, the heaviest components is of 25 kg, a labour can easily lift it.
By adopting Aluminium Formwork System in the project not only it gives the better quality of construction and but also increases the speed of construction and reduces the cost since some of the construction activities are completely eliminated and others are reduced to an extent. Also it eliminates the need of plastering, thus decrease the time and cost at finishing stage to large extent
