Formwork is essentially a mold that receives the concrete slurry and supports it till the concrete has sufficient strength to support itself. It is constructed as a negative of the shape intended for the concrete [2]. The most common materials used for formwork are Timber, Plywood, Steel, Aluminum and Plastic.

Formwork systems are complex assemblies arranged in such a manner that concrete can be poured in the resulting cavity with desired finish.

The desired qualities of a good formwork system are:

-erected and deshuttered fast

- minimize the quantity of concrete and achieve good finish

- be easy to assemble

- have high overall cost savings

- improve safety of site personnel

What are Formwork Systems?

What is Formwork?

The type of material to be used depends on the nature of construction as well as availability and cost of material. Commonly used materials are: Timber, Steel, Aluminum and recently Plastic

Formwork system consists of some basic components that help in load transfer and  retaining shape for the form. These components include- Shoring, Panels, Beams/girders along with their connectors. Apart from these, there is often a hoisting mechanism involved.

The various types of formwork system now available in market are discussed here. These include- Slab and beam Form, Column, Wall, Flying, Sliding,Tunnel, Gang, Special and Permanent forms
