Formwork is the mold that you can use for shaping the concrete structure. You cannot make good concrete from a bad mold; for this reason, formwork is essential for producing good concrete. With the help of formwork, you can pour the concrete, cast it in the desired shape, and attain initial strength. Also, concrete hardens and matures in the formwork. RCC helps build tunnel lining, bridges, hydropower dams, irrigation headwork, etc. in other countries, referring to it  as  shuttering instead of formwork.

What are the Components of Formwork

You have to remove the formwork when concrete is at its suitable strength. Stripping is the process of removing the formwork. After stripping, you can remove its components and reuse them in other construction processes or other parts of the work.


There are many parts that altogether make a formwork. Below are the components of formwork, such as:


Props give the vertical support in the formwork; it carries the shuttering load and other loads, such as

  • structure load,
  • material load,
  • workman crafts load,

In the traditional formwork system, you can make it with timber, but if it is for heavy construction, it should be made of aluminum or steel.


A formwork tie is a tensile unit used for connecting opposite sides of the formwork. It helps to make a balanced connection or to resist the adequate pressure of the fresh concrete. Usually, it comprises an internal tensile member and an external supporting device. Snap-on ties, flatties, ring ties are known as disposable ties. Generally, you can twist them and they return to a specified distance from the concrete surface with a relatively low capacity. Coil ties and bolts are examples of ties, some of which remain in the cast, while some are reusable.


Anchor is a device utilized for fixing the form to the pre-placed concrete with sufficient strength. The equipment usually is embedded in the concrete during placement. The bearing capacity of the anchor depends on the following factors:

  • The embedded position and depth in the member
  • The type and strength of the concrete embedded in the anchor.
  • The material and shape of the anchor
  • The area of contact between the concrete and the anchor.

Spacer from Side

The side spacer is equipment that you can use for maintaining the required distance between the vertical formwork and the steel bars.


It is a device for hanging the formwork load from structural steel, precast concrete, or other components.


You can use the formwork in different sizes and shapes according to the requirements of the Construction Projects. The formwork costs you around 20% to 25% of the price of the structural building work. Also, it may be higher than this for constructing bridges. To reduce the cost of the formwork, it is crucial to design economical formwork types and mechanize its construction. The article covers components of formwork in detail.
